Alright, let’s get you set up with a super simple round crochet pattern for a cup holder! This will be flat and just the right size for most standard cups.

Materials:

Medium-weight yarn (cotton or acrylic works great!)
Crochet hook size H/8 (5.0 mm) – adjust if your yarn label suggests otherwise
Scissors
Yarn needle for weaving in ends

Abbreviations (US Crochet Terms):

ch = chain
sl st = slip stitch
sc = single crochet
st(s) = stitch(es)
beg = beginning

Pattern:

Round 1: Ch 2 (doesn’t count as a stitch), work 8 sc into the second ch from the hook. Sl st to the first sc to join the round. (8 sts)

Round 2: Ch 1 (doesn’t count as a stitch), 2 sc in each st around. Sl st to the first sc to join the round. (16 sts)

Round 3: Ch 1 (doesn’t count as a stitch), *sc in the next st, 2 sc in the next st; repeat from * around. Sl st to the first sc to join the round. (24 sts)

Round 4: Ch 1 (doesn’t count as a stitch), *sc in the next 2 sts, 2 sc in the next st; repeat from * around. Sl st to the first sc to join the round. (32 sts)

Round 5: Ch 1 (doesn’t count as a stitch), *sc in the next 3 sts, 2 sc in the next st; repeat from * around. Sl st to the first sc to join the round. (40 sts)

Round 6: Ch 1 (doesn’t count as a stitch), sc in each st around. Sl st to the first sc to join the round. (40 sts)

Finishing:

Fasten off your yarn, leaving a tail of about 6 inches.
Thread the yarn needle with the tail.
Weave the tail through the stitches on the back of your work to secure it.
Trim any excess yarn.

Tips and Variations:

Size: If you want a slightly larger or smaller coaster, you can add or subtract rounds, making sure to increase evenly.
Color: Get creative with colors! You can change colors every round or every few rounds for a fun look.
Texture: For a bit more texture, you could try using half double crochet (hdc) or double crochet (dc) stitches instead of single crochet. Just remember that the coaster will be a bit bigger and have a different feel.
Edging: For a neat edge, you can work a round of reverse single crochet (crab stitch) after Round 6.
