this is my version of the "roll your own" case. it's completely crocheted (out of possibly the ugliest yarn ever created). aside from the yarn, i really like it, and it didn't take long at all.
here's a close-up of the individual compartments (running-stitched from the same yarn...edges also sewn up with that god awful stuff):
this is the edge of the flap (shell stitched with a chain threaded through for the tie):
...and here it is rolled up and tied:
when i was stitching the hook and scissor pouches, i left the ends raw...that way, you can see better where the hooks go, plus it gives you a cool little fringe.
were i to do it over, i'd definitely use a thinner (and prettier) yarn so that it didn't make such a chunky roll.
