I came to the How-To yesterday and was so inspired that I'm now on deviantART. Hope you have copies of the book at your booth because Victoria and Otto are fantastic! Thanks for sharing their story and yours.
I think this is my favorite work featuring Otto and Victoria: Most of the sewing I do is costume-work; and I have an 1874 Singer that I'm slowly restoring. Sometimes I wish that I had as many arms as Otto, though- it would make the projects go by faster, I know that!
I absolutely love the details in all of your pictures... but when I saw the "kesinger" treadle sewing machine I just about fell out of my chair. We have the exact same type of sewing machine! No octopus to help us, but it's still in working condition.
