It's taken me awhile to figure out what's what with fabrics and I would give yourself some time . In the meantime sort them into colors or/ and sizes, put them away( or not) and think about what values they are( light medium dark) and what kind of fabric they are - polyester blend? Or knit or cotton blend. Silk, linen. Etc. if you have a lot of novelty prints, you could make an. " I spy" squares quilt. I love the idea of foster kids quilts!enjoy and have fun with them!
