This was smart of you! What a great idea because everything seems to be just out of reach when you are laid up.

Idea .... one could just take the whole top of a pair of jeans, sewing across at the crotch. Pockets already made for you, with one jumbo one between the front and back of the pant top. If you wanted to jazz it up, then add a printed lining!

Here’s a quick one I made. Approx 24” length by 14” across. Double sided, light layer of fusible. I just guessed on pocket size. Front & back right sides together, pockets inside & ties. Leave a few inches for turning, etc. i staggered diviiding the pocket stitching one in half and the other 1/3 & 2/3( larger pocket worked well for mail, magazines, etc.
if I were to make this again, I would have a velcro flap over one pocket.
This stayed in place well when putting in the car. Hope the picture shows up.

I use a walker. There are two types. One is a folding aluminum walker with 2 front wheels that you push along. There's many attaching by velcro tote bags for the folding walkers. There are a few for the walkers with 4 wheels which are called rollators. It's important that you know which type walker she has. I have both but an attached tote bag on only the folding one.

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.
