Well, my stash is...heck, I don't have my inventory at home. Well over 2000 meters. Last count, I have 14 or 15 tubs of the stuff, wrapped on comic board neatly and double stacked in each tub. Out of that, I have about half a tub of fabric I'd never use (you know the fabrics bought online, bought on sale, didn't come out as expected, etc.), half for my husband's fabrics and one tub for my daughter. Doesn't include my muslin fabrics, though.
And I inherited my mom's fabric, which is a good half again as much as I have. And no, I haven't gone through it. I have no idea what she has fully.
Recalling all this fabric is one of the few things my synesthesia is actually good for. I can't tell you what tub my fabric is in most of the time (I can get in the general area, but not exact tub) but I can tell you what the fabric is and color (like dragonfruit satin) but not content. And I can tell you the year and day of the week I bought it, although not always the month.
