I just found a book in a thrift shop "Color and Cloth" - that is all about choosing fabric, and seeing what one has, etc.
helpful: organizing fabrics by the color wheel (solids/or blenders I guess) and another color wheel for prints.
I'm going to do this...and see what my collection lacks, not that I'll rush out and buy any...I laugh at myself because when I joined in Feb. I posted that I didn't have any scraps. Ha! that didn't last long.
Moving does have a way of forcing your hand!
