Argo Tea Bottle Cozy

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.
