I had a little difficulty finding beads with large enough holes to go through the braided drawstring, and ended up cutting away some of the threads and just leaving a couple. If I make it again, I'll shop for the right beads instead of just raiding my bead stash, as it wasn't really acquired with beading on yarn in mind.
I don't use the Goddess deck much. I have a collection of perhaps twenty decks, of which I only use 3 or 4 regularly. But since the original pattern (which you can find here) was designed with the Goddess deck in mind, I figured that was the deck it belonged to. I can almost hear the waves of smugness coming from my bedroom: "I have a nice knitted tarot bag. You just have a cardboard box."
If it becomes too much, I may have to launch onto a lifetime project of knitting enough bags for all...
