Flip and Set Tool Demo
 

Yes, but so expensive!

need this for the quilt I'm working on now, I picked a block to make now I want to set them together on an angle. this tool woulds work wonders for me. Have to call Joann to see if they have it.

I have seen the big half triangle rulers for this but I like the way this one flips into a much smaller piece for storage. Can't believe this has been out for 3-4 years and this is the first time I am seeing it. Thanks for sharing.

It is pricey, but it sure would be handy. Maybe I'll get lucky at a thrift store.

I bought this ruler years ago when Walmart here closed the old store and moved to a SuperCenter. It was marked down to a few dollars if that much. It's hanging on my wall and I have never used it. I didn't really know how. Thanks for the youtube link. Never pass up a specialty ruler on clearance. Like styles, it will come back as being the 'new' thing. LOL

Based on the shape, a right angle ruler would work just as well.
