I have designated one cabinet just for projects and/or UFO's. It has 4 shelves so enough for at least 8 projects/UFOs. As I decide what fabrics to use for each project I add it to the pile on that shelf. If its a bolt of fabric I pin a note to the bolt telling me for which project/UFO it goes to and place it on top of the shelf unit. If I have 2 projects on top of each other I make sure the fabrics are so different from each other I'll know which goes to which plus I add the pattern to the top of the project to separate them from each other. Right now I have 14 projects in the shelf unit. Waiting to quilt the last UFO quilt top before I get to start on this year's projects. Told myself I couldn't start a new one till I had all the others done.
