Tim Holtz has put together an online class (2 weeks) that so far has been amazing. I've been stamping for almost 20 years and didn't know half of what he is explaining. Whoever knew the reasons why pigment ink did this or dye ink did that. He takes a subject and usually demonstrates 3 different techniques. I've been following along each day and try to duplicate. Boy, does he make it look easy. But getting the same results are NOT. A lot of folks have put their creations on their blog. I'll have to think about that for a bit - maybe a do over or TWO.
