This ruler is not an inexpensive investment but it is worth it if you like to make half square rectangles. It makes them in many sizes. I am an experienced quilter and find with other methods there is a tendency for wonkiness in the block shape. I always iron my seams open. With this ruler you have to iron to one side. After I do the trimming, I then iron my seam open. An extra step but a perfect block!
Haven't started the project yet.
Great customer service when I needed this item in a hurry. It was in stock and they even put it aside for me.
Well, since I have a HST one, this one looks promising. Only made one trial block as I am into getting some projects finished for the holiday season. So far an excellent product.
