This heart coaster crochet pattern combines a pink lace center, rounded lobes and a fine contrasting outline. I like the pink-and-gold pairing because the narrow trim makes the scallops easy to see without taking attention away from the heart shape.
A coaster spends much of its time underneath a cup, so the flat center matters as much as the border. Here, the heart starts at the bottom point, grows into a small triangle, and gets two rounded fans at the top. Counting the border before adding the shells helps keep the edging balanced.
Follow the instructions in US crochet terminology, then use the two diagrams at the end as a visual reminder of the shaping and edging.
Heart Coaster Crochet Pattern: At a Glance
- Construction: eight rows for the triangular center, two fan-shaped lobes, a single crochet foundation border, pink shells and a contrasting outline.
- Level: confident beginner comfortable with double crochet, treble crochet and working into row ends.
- Appearance: a flat pink heart with lace openings and a scalloped edge.
- Finished size: varies with yarn, hook and tension. Measure after blocking.
Materials for the Heart Coaster Crochet Pattern
- Smooth cotton yarn in pink for the center and shell border.
- A small amount of beige or gold-colored cotton for the outline. A slightly finer yarn gives a delicate edge.
- A hook suitable for your main yarn. A 3.5 mm hook is a starting point for medium cotton; adjust to obtain an even, flexible fabric.
- Yarn needle, scissors and removable stitch markers.
- A flat blocking surface, if needed.
For this heart coaster crochet pattern, choose the yarn for its stitch definition and care instructions. Cotton makes the openwork easy to see. Match the outline yarn to the main yarn’s care requirements, and keep glittery or slippery trim out of the design if it makes the edge difficult to control.

Pattern Notes
Work Rows 1–8 back and forth. The starting ch 3 counts as the first dc. On the next row, work the final stitch into the top of that turning chain. When instructed to add 2 dc to the first stitch, work them at the base of the turning chain; together with ch 3, this makes a group of 3 dc.
A ch-1 space counts as one position in the lace rows. On the following solid row, work one dc into each ch-1 space, rather than into the individual chain. The rows with lace still have 19 positions, even though fewer than 19 actual dc stitches are present.
Keep the turning chains relaxed. A tight chain can draw the sides inward, while an oversized chain leaves a loose edge. Check your count at the end of each row before continuing.
Heart Coaster Crochet Pattern: The Center
Rows 1–4 — Bottom Point and Increases
- Row 1: ch 4. Work 2 dc in the 4th ch from the hook. The first 3 chains count as a dc. (3 dc)
- Row 2: ch 3, turn. Work 2 dc in the first stitch, 1 dc in the next stitch, and 3 dc in the final stitch. (7 dc)
- Row 3: ch 3, turn. Work 2 dc in the first stitch, 1 dc in each of the next 5 stitches, and 3 dc in the final stitch. (11 dc)
- Row 4: ch 3, turn. Work 2 dc in the first stitch, 1 dc in each of the next 9 stitches, and 3 dc in the final stitch. (15 dc)
Rows 2–4 add two stitches at each side, increasing the total by four each time. The original foundation chain at the bottom remains the point of the heart. Mark it now so it is easy to find when working the border.
Rows 5–8 — Lace and Upper Edge
- Row 5: ch 3, turn; 2 dc in the first stitch. [Ch 1, skip the next stitch, dc in the next stitch] 6 times. Ch 1, skip the next stitch, then 3 dc in the final stitch. (12 dc and 7 ch-1 spaces = 19 positions)
- Row 6: ch 3, turn. Work 1 dc in each of the next 17 positions, treating each dc and each ch-1 space as one position. Dc in the final stitch, which is the top of the previous turning chain. (19 dc)
- Row 7: ch 3, turn. [Ch 1, skip the next stitch, dc in the next stitch] 8 times. Ch 1, skip the next stitch, then dc in the final stitch. (10 dc and 9 ch-1 spaces = 19 positions)
- Row 8: ch 3, turn. Work 1 dc in each of the next 17 positions. Dc in the final stitch. (19 dc)
Fasten off after Row 8. Lay the triangle flat with its point downward. Count the 19 stitches across the top from left to right and mark stitches 1, 5, 9, 10, 11, 15 and 19. Stitch 10 is the central notch.
Make the Two Rounded Lobes
Keep the same side facing you for both lobes. Each fan uses nine top-edge stitches, with the middle stitch serving as the fan’s center.
- Left lobe: join pink with a sl st in top-edge stitch 1. Skip stitches 2–4. Work 7 tr in stitch 5. Skip stitches 6–8. Sl st in stitch 9. Fasten off.
- Right lobe: join pink with a sl st in stitch 11. Skip stitches 12–14. Work 7 tr in stitch 15. Skip stitches 16–18. Sl st in stitch 19. Fasten off.
There are 14 tr altogether. Do not add treble stitches to stitch 10: it stays between the two fans and forms the notch. The four slip-stitch anchors are at stitches 1, 9, 11 and 19.
This part of the heart coaster crochet pattern changes the triangle into a recognizable heart. Spread the fans gently before beginning the foundation border, and keep the notch marker in place.
Single Crochet Foundation Border — 68 Stitches
With pink and the same side facing you, join with a sc in the central top-edge stitch 10. This is border stitch 1. Travel from the notch around the right lobe, down the right side, around the bottom point and back up the left side.
- Sc in the right inner anchor at top-edge stitch 11. (1 sc)
- Work 2 sc in each of the right lobe’s 7 tr. (14 sc)
- Sc in the right outer anchor at top-edge stitch 19. (1 sc)
- Work 2 sc around each of the 8 row-end posts down the right side. (16 sc)
- Work 3 sc in the original foundation chain at the bottom point. (3 sc)
- Work 2 sc around each of the 8 row-end posts up the left side. (16 sc)
- Sc in the left outer anchor at top-edge stitch 1. (1 sc)
- Work 2 sc in each of the left lobe’s 7 tr. (14 sc)
- Sc in the left inner anchor at top-edge stitch 9. (1 sc)
Including the first sc at the notch, the total is 68 sc. Join with a sl st to the first sc. Do not count this joining slip stitch as an extra border stitch. Keep the same yarn attached.
The row-end stitches go around the side posts of Rows 1–8. The anchor stitches go into their top loops; these are separate placements. Do not work into the skipped top-edge stitches hidden beneath the fans. The middle of the 3-sc point is border stitch 35.
Heart Coaster Crochet Pattern: 17-Shell Border
Begin at border stitch 1, where you just joined. Do not add a turning chain. Repeat the following around the whole heart:
[Skip 1 sc, work 5 dc in the next sc, skip 1 sc, sl st in the next sc] 17 times.
The first shell is in border stitch 3. The last slip stitch goes into the starting border stitch 1 and closes the round; do not add another repeat. You now have 17 shells, 85 dc and 17 slip-stitch anchors.
A shell falls in stitch 35 at the bottom point, and a slip stitch stays at the top notch. Fasten off pink. If the count is wrong, check the foundation border before adding the contrasting yarn.
Contrasting Outline
Join beige or gold-colored cotton in the first dc of any shell. Ch 1; this chain does not count as a stitch. Work 1 sc in that same dc and 1 sc in each of the next 4 dc. Sl st in the pink slip-stitch anchor between this shell and the next.
Continue [1 sc in each of the 5 dc of the next shell, sl st in the next pink anchor] until all 17 shells are outlined. Join to the first sc and fasten off. The outline contains 85 sc and 17 slip stitches, excluding the final join.
Keep the outline loose enough to follow the pink edge. I like a fine contrasting yarn here because a heavy outline can overpower the open center of this heart coaster crochet pattern.
Optional Inner Gold Outline
For the extra inner accent shown in one of the Pins, add surface slip stitches along the pink foundation border, just inside the shells. Hold the contrast yarn behind the coaster. Insert the hook from front to back through the first border stitch and pull a loop to the front. Insert through the next border stitch, pull another loop through the fabric and through the loop on the hook. Continue around the heart with loose surface slip stitches, following the notch and point. Join to the first loop, fasten off and secure both tails on the back.
Finishing Your Heart Coaster Crochet Pattern
Weave each tail through several stitches on the back, changing direction before trimming. No fabric glue is needed. If the heart needs shaping, dampen or wash it according to the yarn label, press out excess water gently and lay it flat.
Arrange the lobes evenly, open the lace spaces and shape the bottom point without stretching the shells. Leave it to dry completely. Follow the label before using steam or heat, especially if either yarn contains a blend.
The lace openings are decorative, so moisture can pass through them. Use the coaster under ordinary cups and mugs, and wipe condensation from the table when needed. This design is not a substitute for a heat-resistant trivet under cookware.
Heart Coaster Crochet Pattern FAQ
Why does Row 5 have only 12 dc?
Its seven ch-1 spaces also occupy positions across the row. Twelve dc plus seven spaces make 19 positions, ready for the 19 dc in Row 6.
Why is the border curling?
Check the 68-sc foundation count and the two stitches per row end. Tight edging or a thick contrast yarn can pull the edge inward. Ease your tension rather than adding uncounted shells.
Can I make this heart coaster crochet pattern in one color?
Yes. Use the same yarn for the outline, or stop after the pink shell round for a simpler finish.
How can I make a matching set?
Use the same yarn weight, hook and tension for each heart. Reverse the pink and beige colors for a coordinated pair, and block both pieces to similar dimensions.
