Great job it's beautiful
You can order from Harbor Freight and they are called carpet cutter blades and they are really cheap. Go online and look for yourself.
Since it's a diverse group how about "Anything Goes in Quilting"
I know this won't help much, but i bought this fabric about 11 years ago in an upholstery store and made cushions for a rattan loveseat/chair. I painted the wall behind it with a coordinating mural, and one of the monkeys sitting on top of a door frame!
