you could easily incorporate the socks into a quilt in several ways, you could applique the whole sock down by hand or machine, you could cut the sock in half(right side/left side) and back it with fusible web then applique or you could do the same but use iron on stabilizer then incorporate by appliqueing it onto a block or just like fabric using a 1/4 inch seam allowance & paper piece it. I've used socks and pockets from jeans to make little pockets to tuck things into on quilts by just sewing down the back of the sock top & leaving the front open.
