You might have too much variety in your fabric stash if...
You go to the garage (or where ever your surplus stash lives), looking for a piece of lycra. You see, I'm working on a birthday suit. I mean a swim suit for my birthday.
And the only piece of knit fabric that you find is...
A fuzzy, curly black, soft, fleece that looks like it would make a lovely teddy bear.
And now I can't erase the image of a thong / g-string made out of this fabric from my brain.
BTW. I did find the lycra bin. And a couple pieces of silk that I had COMPLETELY forgotten about.
