Everyone's w/could be different ...
depends on how tight you have it packed,
how much air space you have around it, and
how heavy/lightweight the fabric is.
If it is something you realllllllllly want to know .......
then my suggestion would be to measure some of your stash.
Let's say you had a total of 17.8 metres that weighed in at 15 lbs.
(
Note: have no idea how realistic that weight would be for the amount of fabric.)
Then weigh all your containers .... but be sure to deduct the weight of all the bins.
You could then do the math, and have somewhat of an estimate.
But do you really want to know?
