I don't have a specific idea for you, but what I do is when I see a quilt I'd like to make I print out a pic of it and put it on the wall in my sewing room. I look at them as I'm up there working and the next project often pops right out.
I also like to bounce back and forth. I have a few quilt tops that need quilting but right now I'm making a jacket for myself. I felt like I needed a change and I have a lot of garment fabric around so I made myself something new to wear!
