What a beautiful mason jar cozy! Thank you for sharing the pattern and for including the instructions for the pineapple cluster stitch–new to me.
Just one question…you say large mason jar..is that a 2 quart jar? That’s what it looks like in the photo. I have a few of those that need new lids, so instead of getting lids I’ll just turn the jars into beautiful holders for my desk etc. and for gifts to friends who don’t knit or crochet. I admire your creativity.
Hi Trish,
Thanks so much! I’m so happy you find joy in it. Gifts for friends is a wonderful idea! A 2 quart jar should work fine. You can also adjust for the mason jar you are using. When you are doing the beginning increasing circle, stop when it is the same size as the bottom of the jar, then continue on with the pattern. The pineapple cluster is one of my favorite. You can find it in a few of my designs. Good luck!
