This coaster has the same edge as my Baby Hat Pattern and my Lacy Scarf Pattern. It is my favorite edge. I am make a bunch of these coasters for my next craft fair.
So here is the pattern:
Using worsted weight cotton yarn and a G hook.
Round 1: Ch 2, 6 sc in second chain from hook, I did not join and worked on to the next round.
Round 2: 2 sc in each of the next 6 sc, slip stitch in the next sc, ch 3.
Round 3: *2 dc in the next sc, dc in the next sc* repeat around ending with 2 dc, join at top of ch 3, ch 1
Round 4: sc in top of ch 3 and in next dc, 2 sc in next dc
*sc in the next 2 dc, 2 sc in next dc:* repeat around, slip stitch in first sc.
Round 5: Ch 7, dc in the 4th chain from hook dc again is the same sc where the ch 7 began,
*sk 1 sc, dc in the next sc, ch3 dc in the top of dc just made, dc in the same sc as the previous dc.* repeat around and join with the 4th chain of the beginning ch 7. Finish off.
