Review on ✨ Enhance Precision with Triangles Roll Half Square Paper Grid by Bradley Wacks

I like how they give me accurate half square triangular blocks but I have two comments I wish I had known beforehand: 1) If it inside says the finished block is 4.5 inches, they mean the size of the finished sewing. 2) After you cut out the pieces and press down, the square is slightly smaller than it should be. To make a finished 4.5 inch sewn block, the cut block would need to be 5 inches, but they are closer to 4.875 inches. Mixing these blocks with others can cause problems.
