I was thinking hmmm... I'm pretty sure that Home Depot or Lowes sells plexiglass.. and they did. Lowes will actually cut it for you however the man that normally uses that machine says that it doesn't cut EXACTLY perfect so I figured I would give it a go on my own. I did pretty good. I figured I would only be out $2 if I messed it up, so why not give it a go..... I'm happy with it - and I got a few of them out of my 8x10 piece of acrylic... including a 6.5" one - okay, it is a hair under 6.5 but I will not tell the quilt police if you don't....
Here is the tutorial on how I made it.. and here's a picture of my first table runner made with it. It is a bit of an oops... but it will do... but not for my bedroom. I've begun piecing for the bedroom ones. I'll post pictures after they are a bit more under way :)
