I don't understand why people do this yrs. ahead & planning to use it in retirement. Our tastes chg. so much. Fabrics become out of style. Newer & better things come along.
Unless you're retiring in the next yr. or two, I don't understand the need to stock up for the future.
I used to make my kids clothes so when I come across fabric I didn't use, it's is the type that requires heavy ironing. The new stuff is so much nicer & I don't use any of the old stuff. Just something to think about.
