Every Oct. I go to the Pacific International Quilt Festival in Santa Clara, CA so I can hit the "Superior Threads" booth in the merchants mall...where I purchase a ton of threads! The more you buy, the cheaper it is. I usually focus on buying colors I will use in projects for the coming year, plus, I buy at least one "just because" and later find a use for it! Buying at PIQF I save on postage, plus get a discount!
