That's very cool. I honestly had no idea these panels were out there (I don't really get out of Creation Station much). If you get a chance, hop by Creation Station & meet Kimmi, who is giving our millinery panel ("The Glad Hatter", 5:30 pm Saturday, Directors suite) & our panel on steampunk/Dickens-era cosplay ("How to Hustle Your Bustle" 8 pm Sunday, Directors suite). She's giving a workshop on making corset boning in our Creation Station at Orycon. If you're involved in Orycon, maybe we could connect you.
Moreover, Andi from Cosplay, and Shelley from Creation Station, are offering another panel somewhat related to your topic. It's "Pattern-Making Software and Cosplay", held at 11 am Saturday in the Creation Station Panel Room (i.e., the Directors Suite, 3rd floor, Hilton side).
Here is its event description:
"How often do cosplayers search for a commercial pattern, only to find it is out-of-print, the wrong size, or simply doesn't exist? Wouldn't it be nice to choose from various pattern elements to create a custom-fit pattern from your home computer, instead? In this panel, we will show the methods to achieve great fit and drafting, using the automatic and manual features of one of today's most versatile pattern-making software programs."
