I have three 3" binders with index tabs listing the categories: baby quilts, 3D quilts, House quilts, X-blocks, Bento Box, Modern, Flowers, Paper Piecing, Crafts and Miscellaneous Ideas. When I get ideas or jot down notes at quilt shows, I put them into the sheet protectors that have a bottom and two sides so that they don't fall out. Love to sit on my bed leafing through the binders for inspiration, a lot of which has come from the Pictures section on this board.
