Sigil, The Pattern
I have converted my notes on Sigil into an actual downloadable pattern, in PDF format, complete with schematics for any who might be interested.
You can find the link to Sigil (and other free patterns I have made) in my Patterns Index or just download the pattern itself by clicking here.

Oooh, Ooooh - thanks Theresa! It's very inspiring!
Theresa, you are so kind to share this marvelous pattern!
VERY generous. Thank you!
OK, the first word that sprang to mind was...."geek"....but in a loving way.
;-)
Wow that's one nice complete looking pattern. Thanks. It should be easy to add a few inches to the bust yes? Could you tell me how much ease you've added so I can get an idea of how much to scale up?
I have to admit, there was definite indulgence of my geeky side when it came to those. However, they also weren't very hard to make. I just make some line drawings using Visio. If you can draw it on graph paper, you can definitely re-create on Visio.
Steph -- I'm in the 34"-36" range, so depending how you slice it there are 4-6" of ease in the design. It should be pretty easy to modify the garment by adding a few more links into the chains at the bottoms, deepenging the armholes a bit and modifying the number of stitches bound off per row for the shoulder shaping.
Thank you thank you thank you! It's a gorgeous jacket, and you are very generous for writing up and sharing the pattern with us. I can't wait until I have the time to knit her. :-)
Thank you!! I love the look of this jacket.
Thanks for sharing your pattern with us! It's very generous of you. I may just knit this someday..I love it!
