I’m learning pattern making myself as well. I have started a thread over in the ‘patterns’ category about making some patterns to ship as examples with the Seamly program. It is important though that these patterns be free from copyright, so I can’t just use McCunn or similar designs because those are copyrighted to them. So the idea is to implement pattern blocks using ‘new’ methods that are not built from their ideas that can then be licensed under something like the GPL or Creative Commons licenses so people can build from them.
Like I said, still learning, but I have a pincussion and a couple versions of a skirt pattern (starting with the easiest and working my way up). I have a bodice block pattern worked out, but I am not super happy with the side seams, so I haven’t posted it to that thread yet.
Feel free to look at those though to get an idea of how to turn measurements into a finished product using Seamly.
