I keep a magazine rack in the sewing room. There are folders in it for everything from curtains - to kids clothing - to quilts. As I print/cut out an idea - it gets slipped into the back slot until I have the time ( - or there's no more room! ) - & then sort them into the folders. Once they are full - out comes the 3 hole punch. There's now 2 shelves full of 3 ring binders. The labels on the spines make finding what category I need very simple - & having presorted into folders makes adding to them easy.
