I donate to Project Linus too. Linus has many many chapters in all states. See if maybe there is one close to you. Here is the chapter listing.

Some of the Linus chapters can provide you with some of the fabric or batting. Our chapter was given 100 bolts of fabric from a quilt shop that was closing and we had quilting parties and used most of it for backings. The chapter also requested donations from the Warm Company, which has been kind enough to send us rolls of Warm & Natural batting for use in Linus quilts. I think it's easier for a charitable organization to get donations from businesses than for an individual to do so.
