How about trying some small projects to practice straight-line machine quilting or FMQ?
I'm just coming out of a dry spell. The only thing I've quilted in the last 5 years were some whole cloth baby quilts that I felt obligated to do. I pushed myself to do those and a couple of other baby quilts. Now I'm back into it full swing. Recently put the quilting frame back up and am hand quilting one quilt. Using my weekly Michael's coupon to buy batting I need for the many quilt tops I've never quilted. This weekend worked on another baby quilt. Pulled out an old UFO that is hand applique. I've got my quilting mojo back!
