If I go in my quilting room & fondle my fabric it will usually get me to thinking in the right direction. Make yourself go in & sit there for 15 minutes with your fabric & your patterns, books. It should get the creative juices flowing, if not the first time you do it, maybe by the 2nd or 3rd day.
I was just this way earlier in the year. I had so many other things taking my attention. I didn't even go out there for weeks! But I'm back at it with a vengeance now. A trip to the quilt shop kick started it this time.
