Hi All, I wanted to respond to this thread because I received a TON of traffic on my blog about the crutch bag pattern. After reading this thread I wanted to share my own experience with using the bag that is on the crutch. I made it to hold small things like a water bottle, a pen, my glasses, my keys etc. Those small things you need without having to lug around a huge back pack. It is true you don't want to make your bag too big or put very heavy things in it. I did use both my rucksack along with this bag and the heavy stuff went into the rucksack.
I was on crutches for 2 months before surgery and 9 weeks after surgery and I will say it was convenient to have something small on the crutch.
If you need help putting one together just let me know! Thanks all! And good luck to you with your daughter's surgery and I hope all will be well!
