I bought a slew of FQs from a company called Ethelbird and Eliza (no affiliation). They weren't cheap, but so unique and good, designer quality fabric. I've made 3 Eye Spy quilts with the variety of FQs I bought. I've also done a few swaps with other quilters (I'll do a swap with you!)
Here's the link to Ethelbird:
