Crochet Coasters and Table Decor Set

Make a five-round cotton coaster, or branch into a larger decorative table mat before adding the shell border. The circle uses double crochet throughout its increase rounds so the stitch height stays consistent. Use the main image for color inspiration; extra flower motifs and accessories shown are not part of these instructions.

Materials and supplies

Washable worsted cotton for an absorbent everyday coaster
4-5.5 mm hook

Crochet terms used

The instructions in Crochet Coasters and Table Decor Set use US terms: ch (chain), sl st (slip stitch), sc (single crochet), hdc (half double crochet), dc (double crochet), inc (two stitches in one), and dec (decrease). Counts in parentheses show the stitches expected after that row or round.

Coaster pattern

Count progression 12, 24, 36, 48 dc branches to eight shells for a coaster or further dc rounds of 60, 72 and more for a larger mat. — **Construction guide:** Finish a coaster with 8 shells after round 4. For a larger mat, continue increasing in dc before adding its border; divide its final dc count by 6 for the shell total.

Work without turning. Starting ch 2 never counts as a stitch. Join each solid round to its first actual dc; start the next round in that same stitch, not the slip stitch.

Round 1: Make a magic ring, ch 2 and work 12 dc into the ring. Close the ring and join. (12)
Round 2: Ch 2, work 2 dc in every stitch, join. (24)
Round 3: Ch 2, repeat (dc, 2 dc in next stitch) around, join. (36)
Round 4: Ch 2, repeat (dc in each of the next 2 stitches, 2 dc in the next stitch) 12 times, join. (48)
Round 5: Repeat (skip 2 stitches, 5 dc in next stitch, skip 2 stitches, sl st in next stitch) exactly 8 times around. The eight repeats consume all 48 stitches. The final slip stitch lands in the last base stitch; fasten off without adding another shell.

Wet-block gently according to the yarn label, keeping the center flat. Do not force it to a promised diameter: no physical sample measurement or yarn quantity has been established. Measure and weigh the first dried coaster before planning a set of four or six. Allow a little extra yarn for tails and tension differences.

Make the matching decorative mat

Follow rounds 1-4, then skip the coaster's shell round. Continue in dc using the table below. On every round, ch 2 (not counted), repeat the instruction 12 times and join to the first actual dc.

Round	Repeat 12 times	Dc count	Shell repeats if stopping here
5	Dc in next 3 stitches, 2 dc in next stitch	60	10
6	Dc in next 4 stitches, 2 dc in next stitch	72	12
7	Dc in next 5 stitches, 2 dc in next stitch	84	14
8	Dc in next 6 stitches, 2 dc in next stitch	96	16

Stop after a complete round when the circle is slightly smaller than your intended mat; the shell border adds width. To continue beyond round 8, add one plain dc per repeat each round, still repeating 12 times. Then apply the same six-base-stitch shell sequence, repeating your final dc count divided by 6 times. Do not reuse the coaster's eight-repeat total for a larger mat.

This is a decorative mat, not a tested heatproof trivet. Use a purpose-made heatproof trivet beneath hot cookware; cotton fiber alone does not establish heat protection.

Tips & troubleshooting

Verify the eight shell repeats

Six base stitches numbered one to six: skip first two, five dc in third, skip fourth and fifth, slip stitch in sixth. Eight repeats consume 48 base stitches. — **Construction guide:** Skip 2, put all 5 dc into the third stitch, skip 2, then sl st in the sixth. Eight repeats consume 48 stitches; larger mats need their own repeat total.

Count 48 stitches before the edging and mark every sixth stitch. Each shell repeat consumes six positions, so eight repeats should bring you back to the beginning without a spare stitch.

Check the coaster under a cup

Let the damp-blocked coaster dry completely, then place it on a flat table and check that a cup sits steadily. Do not use aggressive stretching to conceal an extra shell or a crowded increase round.

Keep a matching set consistent

Use the same yarn weight, hook and round counts for each coaster. Compare the dried pieces before starting the next color so differences in tension do not accumulate across the set.

Frequently Asked Questions

Can I change the finished diameter?

The written five-round coaster has a fixed count. Yarn and hook changes affect its size, so make one before planning a set; measure its relaxed, dried diameter rather than stretching it to a target.

Do the starting chains count as stitches?

No. Use the chains to reach the stitch height and join each round to its first actual stitch. Including a starting chain in the count would create extra positions before the shell edging.

May I sell the finished item?
