I am trying a new approach to make joey pouches recycling some old fleece jackets. They were $.50 at the Op Shop, can't beat that for a bargain. I sewed up the bottom, reenforced the top and cut below the seam. I did use the sleeve to add a binding to the cut edge, but do not think is necessary. The fabric won't ravel and the sag may help the joey get in. The sleeve openings also could be handy if they want to hang the pouch on a pole. I did about 5 or 6 of these now and am waiting for some feedback from the rescue people. It was quick and easy and lower cost than starting from scratch with fabric.
