The pattern has been rewritten to accomodate a standard sized mug (with information on how to alter it to fit other sizes), professionally tech-edited by Eleanor Dixon, and now includes a step-by-step photo tutorial for the smocking stitch pattern. $4.50 of the $5.50 purchase price goes to Médecins Sans Frontières / Doctors Without Borders as part of the Tricoteuses Sans Frontières/Knitters Without Borders fundraising efforts. The pattern is also available for free (download links are at the bottom of this page).
Please note that is is a knitting pattern - a set of instructions for knitting a mug cozy. This is not a finished item, and I do not sell finished cozies (if I did, the retail price would be at least $50). If you are looking to buy a ready to use mug cozy, I recommend going to Etsy and doing a search for "mug cozy" or "coffee cozy." You can see a roundup of my favorites on Pinterest.
