Invest to save you from stress!

So easy to use for squaring up! Love adding new tools into my sewing kit! Bloc locs are never a waste of money!

Love this ruler!

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!

A must for accurate half rectangle triangles!

Great customer service when I needed this item in a hurry. It was in stock and they even put it aside for me.

Bloc loc half triangle ruler

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.
