I had to make hexies and I used Niagara and it made the fabric so stiff that I could take out the paper and sew the pieces together. You are suppose to keep the paper in the hexies until you finish sewing them. I didn't even have to baste them they were so stiff. I usually use Best Press. It seems to be just perfect for my usual piecing. But Niagara works great if you need a lot of stiffness.
