thanks everyone for your responses.
i guess i didn't make it very clear. i want to know how you know how much fabric you bought. 3 meters, 5 meters, 7 meters etc. after you wash it or are just adding it to your stash.
do you put a post it note with the amount and then if you use some subtract if off.
my memories not that good after a few months to remember how much i bought of it and if i used 2 meters from a 6 meter piece, that i would only have 4 meter left.
hope this makes sense.
label: post it note, piece of paper, list on storage container, anything that tell you how much is in each piece instead of having to measure it each time you want to use it.
