Cotton thread size 10
#6 steel crochet hook (or size needed for guage)
19 metal bottle caps (as found on glass coke bottles and beer bottles)
Two rounds in pattern should be approximately the same diameter as one bottle cap.
Chain three at start of round counts as first dc throughout. Join each round with a sl st to the top of ch 3. Be sure to wash and dry all bottle caps thoroughly before crocheting on them.
Rnd 1: 15 dc in 4th chain from hook; 16 dc (ch 3 counts as first dc now and throughout); ch 3, join.
Rnd 2: dc in same stitch as ch 3, 2 dc in each stitch around; 32 dc; ch 3, join.
Rnd 3: dc in back loops only of each stitch around; 32 dc; ch 3, join.
Rnd 4: sk next three stitches, (dc in next dc, skip next 3) around; insert bottle cap so that the open side is seen through the webbing on round 4; join. Finish off.
When you have all your bottle caps made, sew them together with a whip stitch on the back side as indicated in the diagram. Secure all knots. Vibrant colors should be treated to avoid dye run.
Trivet can be machine washed, and should always be machine dried so as to avoid rusting of bottle caps.
