Hi everyone, Here is a link to an Edwardian-era Shirt Waist draft which has been coded into an Inkscape extension. Please take a look at it and let me know if this seems usable. Code comments are welcome, too! sewing_patterns.py<https://docs.google.com/file/d/0BxsnjDIHW4yveE5MZzh... shirt_waist_allington.inx<https://docs.google.com/file/d/0BxsnjDIHW4yv... shirt_waist_allington.py<https://docs.google.com/file/d/0BxsnjDIHW4yvS... Copy these file to the Inkscape user extensions directory, and mark sewing_patterns.py as executable. The Tau Meta Tau Physica blog <http://www.taumeta.org/?page_id=247> covers how the pattern from this book was converted into code. xo, - Susan
