I've made about 3 walker caddies for friends over the years & they all turned out good. One was the "saddlebag" type & the other two were from this link below (If my memory is right). All of them were appreciated & used. I don't have pictures but remember them being easy to make. It would have been nice to have the walker with me when making it so I could design it to fit but my friends didn't seem to have any problems with the ones I made. One was made from old jeans & it turned out really heavy compared to the others that I made.
I would suggest that your friend send you a picture of the type of walker she has so you will at least have something to go by when making the tote.
