I like cutting scraps into usable strips or squares. It's relaxing when I don't feel like sewing.
I also look at my Pinterest pages, where I have stored loads of quilting patterns and ideas. I usually forget what I put there, so looking at them again is great motivation to get the quilting juices flowing. If you like, I will be happy to share my boards with you... they are here:

I have many quilting and sewing boards, as well as knitting and crochet. You can also look at the boards of the many people I am following. Pinterest is endless inspiration and ideas.
