Need to do inventory of my knitting supplies

Being addicted to knitting, you would think that I have every knitting accessory known to mankind.  I must have everything- afterall, I worked in yarn shops with discounts for years, I have a walk in closet nearly dedicated to knitting and an office shared with my husband that displays the rest.  So now that I have a super tight deadline - I now realize that I don't have stitch markers for size #13 needles and beyond nor do I have US13 double pointed needles!  I have 11's and 15's - but I guess my many hat projects never used size 13 needles.  So until I can get to a yarn shop and search for large enough st markers - my great aunt's wedding ring will have to do.  I actually need 2 more stitch markers - but I'm afraid to use my wedding ring and sweet 16 ring in fear of losing this knitting bag!  So - I have decided that I need to write down a knitting list - just like my grocery list that I keep in my purse so the next time I head into a yarn shop, I can pull out my handy dandy list and actually buy what I need and not what I will stash for another decade.
