My pantry and freezer is stocked. My fabric is stocked and if I never purchase another piece of fabric, I could make 20 queen size quilts. Thread too.
We eat left overs, because we were once so poor, all I had to feed pur 4 year old was a slice of cheese and a piece of bread. (Look into a 4 year old eyes sometime that is hungry, that is when I swore to myself I would never be in that position again.)
My DH loves that I don't "SHOP" for things that we don't need and loves my ability to have the same thing 7 different ways. I am very organized, everything in it's place, and not a bunch of clutter. My "4 year old" is now 42 and even though we are far from rich, we never do without.
My grandmother always said, "waste not, want not," and she was so right. As for scraps of fabric, anything 2 inches or bigger is still useful. Old hands can't handle anything to much smaller.
