A kit is a great thing if you like all the fabrics and don't want to have chase them down on your own. I used one kit from Craftsy, on sale for about half price. It was all Kaffe Fassett blue and green prints (expensive, normally!) and they gave plenty of extra. It was beautiful and a very good buy.
By the way, Craftsy has a kit sale going on right now-- some less than half price-- but I think it ends either today or tomorrow.
