I was thinking (that's a problem right there !) that the percentage was how much of a chance that was the next build.I’ve just started using Knife Print. I looked at it before but when they ran a “sale” I signed up. I really like it. There are a lot of templates you can start with and then modify or you can start from scratch. Export the designs as a PDF and then you can print in different scale. The 80, 90, and 95% marked on the pattern are reduced from the 100% original.
