I think I have this ruler someplace and had forgotten about it. I guess I should dig it up and give a try again. I'll need to find the instructions again too.

The top ruler is the O'Lipfa Lip Edge ruler. I have the 4" x 36" one. Walmart has this size for $16. Olfa use to make them but Dritz is the manufacturer now. I guess Dritz bought out Olfa? If your Walmart doesn't have them, they can be ordered by the sewing/craft fabric manager.

The Wonder Cut ruler has been around at least since 2010. Here's a video. I have one but haven't used it yet:

I may have to get this one.

Here's a pattern that I have used. http://quiltbug.com/PDF/Aurora-Borealis.pdf It was great practice for using the Wondercut ruler and I also used the quilt to practice my machine quilting feathers. Sorry I don't have a picture of my finished quilt. I gave it away.

I like both of the rulers in your photo. I cut lots of triangles, so the Wonder Cut ruler is great to have.

Pardon my ignorance, but what are HSTs? Can someone post a tutorial for using this type of ruler? knitpurlgrrl

I have one many years and love it.

Nice ruler. Let us know how you like it.
