I combined the 3 patterns in one bag. I crocheted the pocket and the bottom as in the first pattern and then started knitting, using the lace patterns of the other 2 bags.
I think my pony tail band was just a bit too small and not elastic enough to put the whole bag in the pocket… but never mind; I like the bag as it is.

I added the long and crossed stitch to the lace, as described at this project page.
