I keep a couple boards on Pinterest.. One is All about stash... which is quilt ideas that I could make from my stash... Usually pretty scrappy, and colorful. The other is The Short List...which are the ones that I really want to make, have all the fabrics and patterns for, or are needed for a class project, graduation, or other occasion.
I often deviate, or have a squirrel moment where I jump onto a new idea without any consideration to The Short List, but that's the fun of quilting!
