i sort mine by color mostly,tho i try to keep certain fabrics that were bought for specific projects together so i dont use them for something else!:)
i also buy more than enough for projects so i have scraps left over for another quilt later.i recently made a quilt for myself-have quilted for 40 yrs and didnt have one of my own-made out of scraps from many other quilts i have made.didnt have any $ in it at all.in the process of sorting all fabric into a huge cupboard bought especially for my fabric.congrats on being a new quilter! it's a great hobby.....
