I found this technique on Burdastyle.com I've downloaded the software but haven't had the time to learn or use it. Thought I would share it here and see what response I would get. http://www.burdastyle.com/techniques/pattern-designer-first-steps--... It includes a printable user manual.
Hi Malissa,
I tried it as well, i think there are some errors on the instruction for plotting the dots but in general it's a cool one. Thanks for sharing!
