A question for all you sewing experts.
If a pattern says recommended for silks, knits, etc... basically anything other than cotton/cotton blends, can you still use it OK for cotton/cotten blends?
I kept finding styles I liked but the recommended fabrics were silks or knits. Since I've spent most of the day organizing fabric (and decided I definitely do NOT need any more princess fabric!

I have 3 boys and a teen girl, there is only so much I can do here with Princess fabric.)
Also...I thought this would be a cute idea but am wondering if it will look kind of weird -- putting a Nemo and Ariel fabric together. I was looking at a Nemo fabric I had and thought it would go together nicely with an Ariel fabric I had. They are both under the water so I thought it would work.
