Actually I do not have problems with portraits, that was not what I was thinking about. The way I do my portraits is make a black and white copy of the pattern I am making, playing a bit with the contrast and such. After I print it out, I enhance the lines I want to with a pencil, then cut it out. I go light the first time of cutting. After I have cut what I think will work well, I remove the pattern and compare it to the original. I can now see where it need a little more. I draw some more lines where they need to be right on the pattern and cut again. Repeat until you are satisfied. I always do a stack of at least 4 in 1/4 inch plywood so breakout is not a big problem and I use spiral blades, I have various sizes I use.
What I was thinking was of a way to take a finished cutting and make it into a pattern. For instance, I cut a rose from a PD pic by making a black and white copy and cutting the lines that seem to make it look good. I would like a way to make these finished cuttings into patterns.
I thought that maybe you guys made patterns from finished cuttings, I did not know.
