I prewash all my fabric and then iron it. At first I was really good about measuring it all and putting a piece of masking tape with measurements on the fabric itself. And cataloging it by cutting a small piece and putting it in a notebook. Got tired part of the way and haven't kept either of those two up and really wish I had. Try to keep on top of whatever system you use so you don't have to take huge amounts of time to re-organize it all.
Wish I had known about comic book boards for wrapping fabric around. Wish I had known that the nearest college is a great place to go get plastic drawers in the spring when the kids either throw them in the dumpsters or on the curb (also for small dorm friges, microwaves, and electronics). I wish I had used drawers instead of a chair and would then get storage plus a place to iron, instead of a buried small ironing board that is unusable:oops: However, Spring is almost here, so I am laying odds on snagging a few more, last year I got 5.
I've been pretty good about keeping my magazines in heavy 3 ring binders using those plastic things that the whole magazine fits in, but I wish I had had the energy to copy or cut our the stuff I specifically wanted to keep and get rid of all the ads and junk, at least half of each issue. I wish I had enough bookshelves to put both fabric and books on. I wish I had found this place long ago to sell my books and fabric to get a bit more room :)
