I LOVE my Angler II. It really really helps, especially for smaller HST's. If you are not 'experienced' cut the squares at 3 inches and trim down. Note how you are pressing them and how that MAY distort the triangle. Get into the habit of finger pressing the seam and then setting the iron on the block to press. Try very hard not to move the iron around.By the time you've done a hundred or so, you might want to try cutting the squares 2 7/8 to begin with.
