Bring a little handmade Christmas charm to your morning coffee with this crochet Christmas tree coaster pattern.

Instead of making a regular round coaster and adding a tree motif, this beginner-friendly project is shaped like an actual Christmas tree.

The coaster is worked flat from the wide bottom edge toward the pointed top using simple single crochet stitches and easy decreases.

A tiny brown trunk is added afterward.

The result is a flat, practical holiday coaster that’s perfect under:

Coffee mugs
Hot cocoa
Tea cups
Small holiday candles
Christmas table settings

Make one in traditional forest green or crochet an entire set in cream, sage, cranberry, and green.

Skill Level

Beginner / Easy

You should know how to:

Chain
Single crochet
Single crochet two together
Turn your work
Join yarn
Fasten off
Weave in ends

Materials

Main Yarn

Use Category 4 worsted-weight cotton yarn.

For one coaster, you’ll need approximately:

20–25 yards

in your tree color.

Cotton works especially well because it creates:

Dense fabric
Crisp stitches
Good absorbency
A coaster that lies flat

Trunk Yarn

You’ll need only a tiny amount of brown cotton yarn.

Try:

Warm brown
Camel
Taupe
Cinnamon

Crochet Hook

4.0 mm crochet hook

A slightly firm gauge helps the coaster keep its shape.

Other Supplies

Yarn needle
Scissors
Measuring tape
Blocking mat, optional
Rust-resistant pins, optional

Crochet Abbreviations

This pattern uses US crochet terminology.

ch – chain

sc – single crochet

sc2tog – single crochet two stitches together

st – stitch

sts – stitches

Finished Size

The finished coaster measures approximately:

4½–5 inches tall

and approximately:

4½ inches wide

depending on your yarn, hook, and tension.

This size works well with standard mugs.

Gauge

Approximate gauge:

18 sc = 4 inches

18 rows = 4 inches

Exact gauge isn’t critical, but your fabric should be firm and flat.

If your stitches are very loose, try a smaller hook.

How the Tree Is Constructed

You’ll begin at the:

wide bottom edge

and crochet upward toward the top.

Every second row gets slightly narrower.

This creates the triangular Christmas tree silhouette.

The final row becomes the tree point.

Then you’ll add a small trunk to the bottom center.

Weave in the yarn tail.

Check Your Tree Shape

Lay the piece flat.

You should now have:

Wide flat bottom
Straight crochet rows
Two gradually angled sides
One pointed top

The shape should resemble a simple minimalist Christmas tree.

PART 2: ADD THE TRUNK

Your Christmas Tree Coaster Is Finished

The basic coaster now has:

Green triangular tree
Pointed top
Brown rectangular trunk

You can leave it simple or add one of the optional finishes below.

Optional Border

If you’d like a more defined outer edge, join green yarn at one lower corner.

Work:

1 round of sc evenly around the tree

When you reach the top point:

Work:

3 sc

into the top stitch.

Continue down the opposite edge.

Work carefully around the trunk.

Join and fasten off.

Why the Border Is Optional

The unbordered version has a clean minimalist shape.

The bordered version:

Defines the silhouette
Adds structure
Hides small edge inconsistencies
Makes the coaster slightly larger

Choose whichever style you prefer.

Optional Star at the Top

For a decorative coaster set, embroider a tiny star near the tree point using:

Cream
Mustard
Gold-colored yarn

Keep it flat.

Avoid bulky embellishments on the main mug surface.

Optional Christmas Lights

Use small pieces of contrasting yarn to embroider tiny flat dots.

Try:

Cranberry
Cream
Mustard
Sage

Again, keep all decoration flat so a mug remains stable.

Important: Keep Coasters Flat

Because these are functional coasters, avoid attaching:

Large beads
Buttons
Thick pom-poms
Raised ornaments

Anything bulky can make your mug wobble.

Flat embroidery is a better choice.

Traditional Forest-Green Version

Use:

Forest-green tree

with a:

Warm brown trunk

This is the classic version and works beautifully with cream mugs and natural Christmas decor.

Sage Green Version

Use muted sage cotton yarn.

Pair it with:

Cream napkins
Natural wood
Dried oranges
Evergreen branches

This creates a softer modern Christmas table.

Cream Christmas Tree Coaster

Make the tree in warm cream.

Use a camel-brown trunk.

Add a small forest-green embroidered star or border.

Cranberry Red Tree

Christmas trees don’t have to be green.

A muted cranberry-red version looks beautiful in a mixed holiday coaster set.

Mixed Set of Four

For a Pinterest-friendly color palette, crochet:

1 forest green

1 sage green

1 warm cream

1 cranberry red

Keep all four trunks brown.

Matching Set of Six

For a more traditional table:

Make all six in:

Forest green

Then use two different shades of brown for the trunks.

The matching set looks especially polished for Christmas dinner.

Make the Tree Wider

Add more foundation chains.

Keep an even number of stitches.

Then continue decreasing:

2 stitches every second row

until one stitch remains.

Make the Tree Taller

Instead of decreasing every second row, add more regular rows between decrease rows.

For example:

Decrease row → 2 regular rows → decrease

This creates a taller, narrower tree.

Make the Tree Shorter

Decrease on every row.

This creates a much shorter, wider triangle.

The finished coaster will work up faster.

Mini Tree Version

Use:

DK cotton

with approximately a:

3–3.5 mm hook

Begin with fewer stitches.

Try:

Ch 17

for a smaller tree.

This version can work well as:

Mug mat for espresso cups
Ornament
Garland decoration

Larger Mug Rug Version

Begin with:

Ch 29–31

and continue the same shaping principle.

Make the tree approximately:

6–7 inches wide

for a Christmas mug rug.

Best Yarn for Crochet Coasters

Cotton Yarn

Cotton is my first choice for this project because it:

Absorbs small amounts of moisture
Handles warm mugs well
Produces crisp stitches
Lies relatively flat
Is often easy to wash

Cotton Blends

Cotton blends can also work.

Choose something without too much stretch.

A coaster benefits from structure.

Acrylic Yarn

Acrylic can be used decoratively, but for functional drink coasters I prefer cotton because acrylic is less absorbent and is a synthetic fiber that can be affected by high heat.

For ordinary warm coffee or tea mugs, cotton is the more practical choice.

Don’t Use Very Fuzzy Yarn

Fuzzy yarn can:

Hide stitch definition
Create an uneven cup surface
Make washing harder

Smooth cotton works best.

Scrap Yarn Project

Each tree uses relatively little yarn.

This is a great way to use leftovers from:

Dishcloths
Market bags
Cotton blankets
Previous Christmas projects

Save even tiny brown scraps for the trunks.

Make a Christmas Coaster Gift Set

Crochet:

4–6 tree coasters

Use matching or coordinating colors.

Stack them together.

Wrap with:

Cream ribbon
Velvet ribbon
Natural twine

Add a small handmade tag:

Christmas Tree Coaster Set

This makes an easy hostess or holiday gift.

Pair With a Mug

For an easy Christmas gift:

Choose a festive mug.
Crochet two tree coasters.
Add hot cocoa packets or tea.
Place everything inside a small gift box.

It’s simple, useful, and handmade.

Christmas Table Setting Idea

Place one crochet tree at every seat.

Set the water glass or coffee mug on top.

Coordinate the tree colors with:

Napkins
Candles
Table runner

After dinner, guests can take the coasters home as small gifts.

Use Them Under Candles

A coaster can also sit underneath a small cool or enclosed decorative item, but avoid exposing yarn directly to open flames or hot candle containers.

For functional table use, mugs and cool decorative objects are the safer choice.

Make a Garland

Because the coaster is a flat tree shape, you can also turn it into decor.

Crochet several trees.

Skip the trunks if you want.

Join them to a long crochet chain.

Now you have a Christmas tree garland.

Use as Gift Toppers

Make a smaller version.

Tie it onto:

Kraft paper
Gift bag
Cookie box

The recipient can later use it as a small coaster or decoration.

Add a Hanging Loop

A mini version can easily become a Christmas tree ornament.

Join yarn at the tree point.

Ch:

15–20

Join back into the top.

Fasten off.

Make Matching Napkin Rings

Crochet tiny trees.

Attach each one to a simple chain loop.

Wrap around folded napkins.

This creates coordinated holiday table decor.

Why This Is Good for Beginners

This coaster teaches:

Straight rows
Basic single crochet
Simple decreases
Counting stitches
Basic color joining

Those are useful skills for many larger crochet projects.

Understanding SC2TOG

Insert your hook into the next stitch.

Yarn over.

Pull up a loop.

You’ll have:

2 loops

on your hook.

Insert your hook into the following stitch.

Yarn over.

Pull up another loop.

You’ll have:

3 loops

on the hook.

Yarn over.

Pull through all three loops.

Two stitches have become one.

Why We Decrease at Both Sides

Each decrease row removes:

2 stitches total

One from the left side.

One from the right side.

That keeps the Christmas tree symmetrical.

Common Beginner Mistakes

Forgetting One Decrease

Both ends of a decrease row need an sc2tog.

If you decrease on only one side, the tree will lean.

Losing Track of Rows

Use a row counter or make a check mark after each row.

The pattern alternates:

Decrease row / regular row

Crocheting Too Loosely

Loose fabric can make the coaster floppy.

Try a smaller hook if necessary.

Making the Trunk Off-Center

Count the foundation stitches carefully and place the four trunk stitches in the center.

Adding Bulky Decorations

Keep decorative details flat so cups remain stable.

Edges Curling

Gentle blocking usually fixes minor curling.

Blocking the Finished Coaster

Lightly dampen your cotton coaster.

Lay it flat.

Shape:

Bottom edge
Two tree sides
Pointed top
Trunk

Pin if necessary.

Allow it to dry completely.

Washing Crochet Coasters

Always check the yarn label.

For washable cotton:

Wash gently.
Reshape while damp.
Lay flat to dry.
Lightly block again if needed.

Cotton may shrink slightly depending on the yarn.

How Long Does One Coaster Take?

These are small repetitive projects.

Once you’re comfortable with the decrease sequence, they’re quick to batch-make.

The first coaster may take longer while you learn the shaping.

After that, the repeated pattern becomes much easier.

Can Complete Beginners Make This?

Yes.

If you’re comfortable with:

Chain
Single crochet

the main new technique is:

sc2tog

Once you know that decrease, the rest is straightforward.

Can I Use Double Crochet?

Yes, but the coaster will:

Grow faster
Have larger gaps
Be less dense

Single crochet creates a flatter, firmer surface for mugs.

Can I Use Half Double Crochet?

Yes.

Hdc produces a slightly thicker and softer tree.

You’ll need to adjust the row count because hdc rows are taller.

Can I Use This as a Potholder?

No.

A single-layer coaster should not automatically be treated as a potholder or trivet.

For very hot cookware, use a pattern specifically designed for heat protection with suitable fibers and thickness.

This pattern is intended primarily for mugs and holiday table decor.

Frequently Asked Questions

Is the coaster shaped like a tree?

Yes. The entire coaster forms the Christmas tree silhouette.

Is it worked in the round?

No. It is worked flat from the bottom upward.

What yarn should I use?

Worsted-weight cotton works particularly well.

What hook size is used?

4.0 mm.

How big is the coaster?

Approximately 4½–5 inches.

Is the trunk crocheted separately?

No. It’s crocheted directly onto the center of the bottom edge.

Can I make a matching set?

Yes. The simple construction makes the pattern ideal for batch-making.

Can I turn it into an ornament?

Yes. Make a smaller version and add a hanging loop.

Final Thoughts

Holiday table decor doesn’t have to be complicated.

This crochet Christmas tree coaster pattern uses basic single crochet and simple decreases to turn an ordinary flat piece of cotton crochet into a festive tree-shaped coaster.

Make a classic forest-green set for Christmas dinner.

Mix sage, cream, cranberry, and green for a modern holiday palette.

Or package four coasters with a festive mug for an easy handmade Christmas gift.
