I have a white board on my wall that has my projects prioritized...sort of. For example: I have 2 blocks due for a friend and that's at the top, next is Boomerang Swap, next is wallhanging for living room, next is baby quilt due Feb 27, then baby quilt due April 5, etc. When I finish a project I erase it and put another at the bottom. It helps keep me from being overwhelmed.
My templates are hung on my wall with nails, my fabrics are in clear bins sorted by color. But my scraps are all disorganized in a clear bin, all 5 inch scraps or smaller.
"Quilts to be" are stored together in a clear bin with the pattern on top, colors listed on the outside with erasable marker. The back is stored there, also, if I have enough room.
My closet has batting and batting scraps (and Christmas decorations). I buy quilt backs when on the cheap *under $15- and store them on the top shelves =if they won't fit in the boxes with their tops.
