Something I like to do if I don't have a current project to do is make sampler blocks. I pick out a few that I've wanted to try and different scraps, etc. to make them from. When I have made 3 or 4, and one of them was fun and I enjoyed it a lot, then that will be my next project and I'll use that as the base for my next quilt.
Sometimes it's the first or second one that trips my trigger, so that's when I am inspired and put away the samplers and start the next project.
It's a fun way to collect blocks for a sampler quilt and to try new things while you are at it.
