I have used printed papers when I was doing a lot of miniatures. I printed mine off a web site as I remember. If the software was very low price It would be worth it -- and if I were going to be doing a lot of them. It definitely saved time when the finished square was only 1 1/2 inch
We all have extra tools that we don't use all that often. I have a chain saw that I use only when I cut down a tree or large limbs -- But I still need it.
