I'm not a prewasher, whether it's a precut or not! Luckily, I like the crinkly/old look, so it's all good. I don't buy a lot of precuts, b/c they aren't generally a good value, but every once in a while, I have to have some of everything in a line, or if there's a really good sale, I buy them. Jelly rolls are really hard for me to use b/c I like they way they look on my shelf - they almost become a decoration themselves instead of a supply. Love the quilt on our bed right now, it's a favorite, and was really easy. Chain of Faith from Moda Bakeshop, Jo's Country Junction. It's also the only time I've used the fabric called for in a pattern.
