Because Laritza is asking about my past knitting with beads, I am making a short post even though it's not lace. I have purchased both patterns and books on knitting lace bags and made perhaps 3 total before stopping. I may do more in the future but lace is more fun. You can use needles in US 000 (the smallest in circular needles I could find) or US 0000 and smaller in straight needles. If you really have a need to go look, here is a little list of places to get stuff for this madness!
