I also don't keep a tally of how much yardage is on each of my bolts, I just go with the flow. One thing I started doing about a year ago is writing on each mini bolt as I purchased fabric, where the fabric came from, when it was purchased, the full price, and the sku# from the receipt, as well as the mfg and title of the design, if any. Joann's is really good about having all of this information print out on their receipt, so if I need to purchase more in the future it's quite simple. I'm not OCD enough to take old fabric to match and get the current details just to write on my bolts, but don't think the idea hasn't crossed my mind! After all, information is power!
