I made this bag for myself. I got tired of lugging my mat to class as it unfurled behind me. It was reminding me too much of my unruly two year old. I've been tinkering with a pattern to come up with the right dimensions. I finally got it dialed in and made one for our school's art auction. I'll donate it, as well as three other brown robin bags. I've made one more out of Amy Butler fabric that is for sale. Now I just need to get around to taking pictures of it to post to etsy.
