Your stash looks wonderful - don't you just love being able to see it? As for yardage - I labeled a few of my pieces (just pinned a scrap of paper with the yardage written on it). But, my boards are 10" so I know one wrap is 20", two is 40" so close to a yard. I just count the wraps for a rough estimate - much like counting wraps on a bolt in the fabric store. Hope this helps! Enjoy your new 'store' :-)
