Kluedesigns,
Thanks for providing the link to the finished quilt pictures. That quilt is awesome! Using the inward points really set off the curve of the center design and they helped break up and add interest to the solid color background, then to use solid binding was another good idea. That one certainly is an 'art quilt' :-)
I see how the edges are buried in the binding &/or the quilt sandwich, it looks very secure. I was a little concerned how durable it might be on a lap throw, but I think it will be ok - the throw is for an adult.
The fabric I plan to use for this throw has a busy pattern so I will use a solid color for the prairie points and test how they look as both innies and outies. I am excited to get started - too bad the prairie points are at the end of the project. lol
