Posted by Meg This little knitted cozy helps to extend the shelf life of the thermic bottles ... and helps you use your extra bits of yarn! Materials: Left over yarn, preferably natural fiber 4 double-pointed knitting needles, small (I used US size 3) Blunt-tipped needle for weaving in edges Cast on 30 stitches using a long-tail cast-on. Divide evenly among 3 needles. Join for knitting in the round, being careful not to twist the stitches. Knit in stockinette stitch until the cozy measures about 3 inches or desired length to fit the bottle. Bind off and weave in tails. I flipped mine "inside-out" so that more of the multi-colored poofs were visible. For instructions on how to knit using double-pointed needles, I recommend this tutorial by knitty.com.
Show the children how to remove the cozy from the bottle like so, touching the cap only and not the metal sides:Provide a basket where the cozies can be placed while the child is working with the material.
