I made a bag that works on both my rollator and my wheelchair!
[First image: a quilted bag with a pocket that is black with grey music notes, a purple and black swirled main fabric, and a strip at the top of white with black music notes attached to a blue rollator walker with 4 purple straps, 2 in the top and 1 on each side
Second image: the same bag attached to the back of a black manual wheelchair, except the side straps are attached to a bar above them]
If anybody's curious, I used the 2300 Simplicity B pattern with some adjustments to the side tabs
