I usually am tired of the colors in my stash and need inspiration so travel about 90 miles (country miles) and look at fresh and bright colors and new fabrics in quilt stores.
I just finished a Grandmothers Dream quilt and am in the same place so I took part in making book bags for economically disadvantaged kids that are preschoolers to get them reading. I embroidered different sayings....What I suggest is fresh ideas, a different color pallette and maybe doing some small projects for others whether church group, quilt group, guild, til you feel refreshed and get your batteries charged. If you like soft colors try bright, etc. Or don't sew for a while work outside til the weather turns icky. I just got an email saying I need to start working on Halloween and Christmas projects, wasn't that mean?!!!!HAHA.
