When I get into a slump, I find that checking out quilt blogs (and now this wonderful forum) gives me great ideas and inspiration to go to my sewing room and do something..anything.
I find that the reason for my slump is oftentimes because I feel guilty that I am not doing the things I need to be doing (like housework) and I need to give myself permission to do the things I "want" to do..
And for the quilter with the boat load of squares, here's my idea: You can make scrappy 4-patches and alternate them with a same-size square of a printed fabric.
