This stackable crochet flower coaster set turns a simple table accessory into beautiful handmade decor. Each coaster has a neat contrasting center surrounded by twelve rounded petals, with a long decorative opening inside every petal.

The visible project is a stack of separate flower coasters rather than one solid cylinder. When eight matching coasters are aligned, the layered petals create the tall floral shape seen in the reference design. Remove one coaster whenever it is needed, then return it to the stack after use.

Description

Each crochet coaster begins with a flat circular center worked in double crochet. Twelve chain loops are added around the center, then covered and shaped to create thick rounded petals with elongated eyelets. The finished motif is flat, structured, and approximately 15–17 cm across.

The main colorway uses a warm cream center with dusty mauve petals. A reversed version can be made with a mauve center and cream petals. Make six to eight identical motifs for a full decorative stack.

Materials

• DK or light worsted-weight cotton yarn
• Color A: warm cream for the center
• Color B: dusty mauve for the petals
• 3 mm to 3.5 mm crochet hook
• Yarn needle
• Scissors
• Stitch marker, optional
• Blocking mat and rustproof pins

For a set of eight coasters, prepare approximately:

• 80–100 g of center-color yarn
• 140–180 g of petal-color yarn

Yarn usage will vary with yarn thickness and tension.

Abbreviations

• ch – chain
• dc – double crochet
• hdc – half double crochet
• MR – magic ring
• sc – single crochet
• sl st – slip stitch
• sp – space
• st – stitch
• sts – stitches
• tr – treble crochet

Pattern Notes

• This pattern uses US crochet terminology.
• Each coaster has exactly twelve petals.
• The center finishes with 36 stitches.
• Every petal uses a three-stitch section of the center.
• Work around the chain loops rather than into individual chains when forming the inner petal outlines.
• Keep the chain loops relaxed and equal in size.
• The oval openings are intentional and should remain visible.
• Block every coaster to the same measurement before stacking.
• The coasters remain separate. Do not sew the finished motifs together.
• Align all twelve petals when stacking so the sides form neat vertical scalloped columns.
• Weave in all yarn ends. The long strands visible during construction are not part of the finished coaster.

Step-by-Step Instructions

Crochet the Center

Using Color A, make an MR.

Round 1

Ch 3. The beginning ch 3 counts as the first dc.

Work 11 dc into the MR.

Pull the ring closed.

Join with a sl st in the top of the beginning ch 3.

You should have 12 dc.

Round 2

Ch 3.

Work 1 dc in the same st.

Work 2 dc in every remaining st around.

Join with a sl st in the top of the beginning ch 3.

You should have 24 dc.

Round 3

Ch 3.

Work 1 dc in the same st.

Work 1 dc in the next st.

Repeat around:

• 2 dc in the next st
• 1 dc in the next st

Join with a sl st in the top of the beginning ch 3.

You should have 36 dc.

Fasten off Color A.

Gently flatten the center before beginning the petals.

Create the Twelve Petal Loops

Join Color B in any stitch from Round 3.

Round 4

Ch 1.

Sc in the same st.

Ch 10.

Skip the next st.

Sc in the next st.

Repeat around:

• Sc in the next st
• Ch 10
• Skip the next st
• Sc in the next st

Continue until twelve ch-10 loops have been created.

Join with a sl st in the first sc.

You should have:

• Twelve ch-10 loops
• Two adjacent sc stitches between neighboring loops
• One skipped center stitch beneath each loop

Do not fasten off.

The chain loops will become the elongated openings inside the petals.

Cover the Petal Loops

Round 5

Sl st into the first ch-10 loop.

Work 13 sc around the chain loop.

Do not work into the individual chains. Insert the hook beneath the complete chain strand so the stitches can slide into an even curve.

Sl st into the small space between the two adjacent anchor sc stitches separating this petal from the next one.

Sl st into the next ch-10 loop.

Work 13 sc around the loop.

Continue around, working:

• 13 sc around each ch-10 loop
• 1 sl st in the separator between petals

Join neatly after covering the twelfth loop.

Each petal should now look like a narrow outlined loop with an open center.

Shape the Rounded Petals

Round 6

Work across the 13 sc stitches of each petal using the following sequence:

• Sl st in the first sc
• Sc in the next sc
• Hdc in the next sc
• Dc in the next sc
• 2 dc in the next sc
• 2 tr in the next sc
• 3 tr in the next sc
• 2 tr in the next sc
• 2 dc in the next sc
• Dc in the next sc
• Hdc in the next sc
• Sc in the next sc
• Sl st in the final sc

Sl st into the separator between this petal and the next petal.

Sl st into the first sc of the next petal.

Repeat the same shaping sequence across all twelve petals.

After shaping the final petal, join with a sl st at the base of the first petal.

Fasten off Color B.

The extra stitches near the center of each petal create the wide rounded outer tip, while the shorter stitches at both ends keep the petal narrow near the flower center.

Finish the Coaster

Thread each yarn tail through a yarn needle.

Weave the tails beneath stitches of the same color.

Change direction at least once so the ends remain secure during washing and regular use.

Trim the excess yarn.

Check that all twelve eyelets are open and approximately equal in size.

Block the Flower

Lightly dampen the coaster.

Place it on a blocking mat with the right side facing upward.

Pin the center flat.

Arrange all twelve petals evenly around the circle.

Pin each rounded petal tip so the motif forms a balanced flower.

Straighten each elongated opening so it points outward from the center.

Allow the coaster to dry completely before removing the pins.

Aim for a finished diameter of approximately 15–17 cm.

Make the Complete Stack

Make eight identical flower coasters.

For the dusty mauve stack shown in the design:

• Use cream for every center.
• Use dusty mauve for every petal round.

Block every coaster to the same diameter.

Place one coaster flat on the table.

Stack the remaining coasters directly on top.

Align:

• All twelve petal tips
• All twelve elongated openings
• The center circles
• The narrow gaps between the petals

Press the stack gently with your hands.

The aligned petals will create the tall flower-shaped column visible in the reference design.

Do not stitch the layers together. Each coaster should remain removable.

Reversed Colorway

For the light flower stack:

• Use dusty mauve for the center.
• Use warm cream for the petals.

Follow the same stitch counts and construction.

Make all coasters in one stack identical so the layered edges remain even.

Tips and Variations

Use mercerized cotton for crisp stitches, smooth eyelets, and a firm finished coaster.

A cotton-acrylic blend can also be used, but very soft yarn may allow the petals to curl or lose their shape.

When the center ripples, use a smaller hook or loosen the increase rounds slightly while blocking.

When the center cups upward, use a slightly larger hook or relax your tension.

Keep all twelve chain loops the same length. Uneven loops will create noticeably different petal sizes.

Push the thirteen single crochet stitches evenly around each chain loop before beginning the shaping round.

Use a smaller hook for a compact mug coaster or thicker yarn and a larger hook for a decorative trivet.

Possible color combinations include:

• Cream center with sage petals
• Mustard center with ivory petals
• Terracotta center with beige petals
• Dusty rose center with white petals
• White center with muted lavender petals

For a smaller stack, make four or six coasters. For the full layered look, make eight to ten.

Avoid adding a thick border around the complete flower. The separate rounded petals and open eyelets are important parts of this design.

Frequently Asked Questions

Are the flower layers sewn together?

No. Every flower is a separate functional coaster. The cylindrical appearance comes from stacking several identical coasters with the petals aligned.

How many petals should each coaster have?

Each coaster has exactly twelve petals. The 36-stitch center is divided into twelve three-stitch sections.

Why are my petal openings different sizes?

The chain loops may have been worked with uneven tension, or the single crochet stitches may not be distributed evenly. Adjust the thirteen stitches around each loop before shaping the outer petal.

Can these be washed?

Cotton coasters can usually be gently hand-washed. Reshape and block them flat while damp, following the care instructions for the yarn used.

Conclusion

This stackable flower coaster set is both useful and decorative, with twelve rounded petals and elegant open details that remain visible even when the coasters are layered. Make a full set in dusty mauve and cream, reverse the colors for a second stack, or choose shades that match your home decor. Once blocked and aligned, the separate motifs create a beautiful floral display that is ready whenever a coaster is needed.
