Now that Christmas is over I can post these pictures. I bought the fleece at the Black Friday sale. I think the fleece was about $3.48 a yard. I can't remember for sure, but it was less then $4.00 a yard. I bought 1 yard of the main body fabric and 1/2 half yard of fin fabric.
I see these bags on Pinterest and decided I could make my own pattern and make the bags out of fleece. Each bag is about 25 inches wide and 40 inches long.
