Here is a tip. When my sister what moving to Alaska, I wanted to make her an all wool quilt, then I saw wool was $30/yd.Is it that expensive to buy it online? Like directly from a fabric shop?
Some other less expensive sources I like are garage sales, if it looks like an "older persons" garage sale I always stop and look for fabric. And used or thrift stores I look through their home wares section at the bedding and curtain areas, sometimes you can find real gems of yardage that someone has made into curtains or the like that isn't "curtain" fabric but cotton. I don't use those sources for swapping fabric, but for my own quilting fabric. For my own use I have also been known to use other then "quilters cotton" for my own quilts.
So a friend of mine volunteers at a thrift shop & they get lots of clothing donated w/ bad stains or rips which they normally put in the trash, turns out this includes lots of 100% pure wool suits/pants/skirts, well my friend was happy to divert these items from the dumpster (which they have to pay to have hauled to the landfill) to me. I cut all the good parts out of each article and in a couple months I had enough for both sides almost queen sized all wool quilt, all it cost was my time , thread & batting. Like ya'll I'm only using new yardage for the swaps, but I do lots of re-use recycle for my own projects
