I found an awesome thing online the other day.... and I am just now getting to post it here...!
Hancock Fabrics has a quilt pattern called Poppies and it has a wedge ruler template in it! I thought that I'd share it with you all :)
It's a free downloadable pdf and it has the template included that you print out and tape together. I'm *pretty* sure it is the 9 or 10 degree ruler template :)
