craftgrrl | Possible dumb question

I see a lot of 'no-sew fleece blankets' and I was wondering if all fleece is no-sew when it comes to making blankets, or just certain kinds. Probably a dumb question, I know, lol, but neither my mom or I have ever worked with fleece before and she's making blankets with a some of her friends for Walter Reed hospital. She's already bought the fabric, and had never heard of 'no-sew blankets' until I mentioned it at dinner. Now she's worried she doesn't have the right fabric. Oops.

So, can I set her mind at ease that her fabric okay?
