I like to do bobbin work actually...learned how in a class once. I bought all the stuff but then haven't gotten back to doing it. Thats why I have that Razzle Dazzle on a bobbin now.
Sorry the appl. e-book wasn't helpful. I've downloaded a few of their free ebooks and I though they made for some interesting reading. However, I'm one of those that if I learn just 1 new thing..I usually think its worth my time. I don't blame you for using your junk mail addy though...I hate spam.
