I made a 12" x 14" tote bag for my walker. I put the handles across the opening instead of opposite sides. Then I cut them in the middle, added velcro and was done. I used a magnetic snap for a closure and inside side pockets for credit card- cash etc, keys, tissues and hand sanitizer. Anything small that you don't want to dig for in the bottom. Works great for me. Most of the commercial bags are too small to carry "stuff" besides the essentials.
