This ice cozy was crocheted from a T-shirt cut into strips to create T-yarn or tarn. I often use an icy brick in my lunch bag and wanted a little cozy for it. The ice block gets wet and has condensation after a while in my lunch bag. Now with the tarn ice cozy, it works wonderfully to keep my lunch bag dry and to capture the condensation from the ice brick.
I cut my T-shirt strips very narrow to make this cozy. Here is my T-yarn tutorial showing how I cut and stretch my strips to create what I like to call curled T-yarn. The only change you want to make for this project is to cut your strips only about 1/4 inch wide. I know this is narrow but if you cut slowing and carefully it works out so you have a nice thin strand to crochet with.
I used the following soap saver pattern to crochet my ice brick cozy. This tarn project and free crochet pattern was a Tarn Along over Recycled into Yarn site. The final measurements are 6 inches long by 3-1/2 inches wide. I did make mine a bit bigger at the beginning and crocheted 3 DC’s in the corners so the icy block would fit and its plenty big. I have 28 stitches in the bag around with 8 crowns at the top.
