My first e-course will be...
Crochet won out this time! This fits best right now because of my granny a day project. My brain is all crochet all the time. Thank you everyone for your responses, I love having such wonderful readers! :) Don't worry, those of you that voted for embroidery and knitting, your time will come. I'll start developing these too now that I know there's some interest out there.
I brainstormed all weekend and think I have a good foundation of ideas for this course. It will have a lot of video elements thanks to my bro-in-law cameraman for offering his services for a Saturday of taping. I'll have more info when I'm ready to start enrollments that I can't wait to share.
