Moda Bake Shop, but I wanted to share a little more here.
You might be wondering what makes these different than regular quilting cotton. I don't know the technical details, but they feel like a lightweight flannel. They are a little fuzzy, but not heavy, they have a little bit more stretch to them, but they aren't difficult to work with.
I also hand sewed the binding down with perle cotton. This is the first time that I have tried this method and it was quick, the binding feels secure, and I really like the effect.
Check out the tutorial for step by step photos. If you decide to make your own quilt, I would love to see photos!
