If you can connect with a clothing-sewer than you'll have lots of scraps. (I worked and had 3 girls with a total of 6 in my family, and a teacher's salary to live on. I made all of our clothes except our underwear..LOL) When I made all of our clothes I had lots of scraps. I didn't quilt.
Many that make their own clothing keep all those scraps and are too frugal to throw them out, but then don't know what to do with them all. Ask me how I know. LOL So I used to bag them up and put them in garage sales. They always sold like hot cakes!
If I'd known a quilter back then I would have given them to that person.
You might try getting on your town/city freecycle page and ask for fabric scraps. Most towns have a freecycle page. My daughter lives in the Texas DFW area and has lots of luck getting for free almost anything that she asks for. Lots of people are just wanting to get rid of stuff and don't care whether they get paid or not. So try that.
Good luck with your quilting. I'm sure with a little creative thinking you'll find what you're needing.
