A true Renaissance woman!

I also knit and crochet (and you saw the soft sculptured dolls. At one time I sewed all my own clothes (until I got too busy or too lazy, not sure which) and I cut my own hair. Milked cows and made butter and cheese. I'm just a person who has to try everything at least once.
I can't keep a clean house though, my house looks a lot like your studio. 
I haven't done scratchboard since I was in high school unless you count my demonstrations for middle-school students... and I haven't done any with my students for over a decade. It is just too dangerous to chance my students with needles or X-acto blades.
