Today I made myself some knitting markers. I have cheap plastic crochet markers, and had seen a recommendation for using "letter" versions from the knitting book I bought to help keep track of where you are in a pattern. A quick look online had them from anywhere from $5 - $10 without shipping.
BAH. A quick look into my beading kit produced letter beads and all the necessary findings & extras necessary to make letter markers. Five minutes later, I had markers A-H that will fit up to a 10 needle. And I still have quite a bit left over to make more...should the mood strike me. LOL
