Sewing challenge: Tote bag for a walker/stroller

*** My elderly mother lives in a nursing home and to get about she needs to use a walker. Attached to her walker is a bag (see below) that holds everything she needs when she is away from her room. However her current bag is looking a very sad and she asked me to make a replacement (2 bags in fact) when I was visiting her last week. I could have just copied mum's old bag, but no . . . I decided to set myself another one of those " sewing challenges " and do something that would push my skills a little!! At this point I could tell you it all worked out well. But I will be completely honest . . . I made one that worked beautifully (for a beginner) and I made another that was my test and no it wasn't perfect. In fact it is a long way from being perfect which is why there is no photos of bag no. 1 But I learn a lot when I made the first bag so bag no. 2 was much easier - I learnt from my mistakes as we like to tell children!! Mum wanted so...
