US terms. The UK name follows in brackets the first time each stitch appears. Turning chains don’t count as stitches unless a step says so. See US vs UK crochet terms and crochet abbreviations.
Do the math
The examples use the gauge above. Put your own swatch into the gauge calculator first, then use your numbers in each formula.
| Step | Formula | Example | Tool |
|---|---|---|---|
| Growth per round | 2 × row height | 2 × 0.57 ≈ 1.1 in | By hand |
| Rounds | diameter ÷ growth per round | 4.5 ÷ 1.1 ≈ 4 | By hand |
Materials
- Worsted (4) yarn (see yarn needed)
- G-6 (4 mm)
- Tapestry needle
Gauge swatch
Just make one coaster and check it lies flat.
Instructions
Coaster
Join every round with a sl st (UK ss) to the first st; the ch at the start of each round does not count as a stitch.
Rnd 1: Magic ring. Ch 2, 12 dc (UK tr) in ring. (12)
Rnd 2: Ch 2, 2 dc in each st. (24)
Rnd 3: Ch 2, *dc in next st, 2 dc in next; rep from *. (36)
Rnd 4: Ch 2, *dc in next 2 sts, 2 dc in next; rep from *. (48)
Rnd 5: Ch 1, reverse sc (UK reverse dc), also called crab stitch, in each st. Fasten off.
Finishing
- Weave in ends.
- Steam flat.
Designer’s notes
- Flat-circle rule: increases per round ≈ 6.28 × (sts per in ÷ rows per in). With typical gauges that comes to about 6 for sc, 8 for hdc (UK htr) and 12 for dc. If your circle ruffles, increase less often; if it cups, more often.
- Keep going to 8 rounds for a trivet (96 sts).
