Just some new thread colors picked up at the local flea market. I rarely buy new new materials. I find it especially stimulating, creatively speaking, to make something work out of a limited stash of resources. Resourcefulness = New ideas. And new ways of seeing things. It's my little Oulipo-like philosophy of sewing and making, in which "constraints are used as a means of triggering ideas and inspiration" (Wikipedia).
Never read a piece of Oulipo work? I recommend starting with Italo Calvino's If on a winter's night a traveler. He is one of my absolute favorites.
