Funny, you should ask. My mother gave me this for Christmas this year. I love the method. I'm working on a project now that needs 2.5 finished half square triangles. I chose the correct sheet within the software, printed out the sheets needed, sewed, cut and they came out 3.0 in. Page clearly states "2.5 finished size". Ughhhh. Had to trim them all back. Guess that's better than not being big enough.
