I didn't waste any time making this cozy for my tea bottle. After brewing some green tea in my bottle, I realized it was too hot to handle. I crocheted this cozy using a size I hook and some Lion Brand cotton yarn. Round 1: ch4 then dc 11 in 4th ch from hook. Sl st in top of 3rd ch of beginning st to join. Ch 3 & turn. Round 2: Make dc in same st as ch 3 then 2dc in each st around. Join w/sl st. Ch 3 & turn. Round 3: 1 dc in back loop of each st around. Join w/sl st. Ch 3 & turn. Rounds 4 - 10: 1 dc in each st around through both loops. Join w/sl st. Ch 3 & turn, except for round 10 where you'd end w/sl st. End off & weave in ends.
