We had a class at quilter's guild last month and the lady had two of the big horse food bags made into totes. They were large. She just cut the bottoms off and turned them wrong side out. I would probably wash them with soap and soda water before sewing the bottom back together and turning the hem for the top. She said there are bird food bags that are absolutely beautiful with neat bird pictures on them. She just used heavy strapping for the handles. I would be willing to try it at least once. I keep telling Cookie to hurry up and eat that big back of chow!
