Wow there are quite a few watercolor crystals out there, huh!! I will be interested in how the crystals are for you Jan after you get to play with them.
I haven't seen any of the ones you mentioned in the stores---I have only seen them online after Sarah and Heidi mentioned them---I had to go see what they were talking about, lol!
The product I was talking about seeing in the Michaels in both the scrapbooking aisle and the art aisle are gels, gesso, pastes---I saw a small jar of gesso in the scrapbooking aisle and it was a small jar and the price (per volume) was really high compared to if you bought some gesso from their art department instead.
Good to know that the colors may not even translate across products within DIs. I wish they could get the color to be closer to the label though---it does make me wonder how they go about designing the labels---I know I'd be bummed if I had worked out the color and after they manufactured everything, the label and paints didn't match each other (but that happens even in watercolors etc)---it would make me feel like I am not representing the product I made correctly (I hope paint stores don't do this! Can you imagine the conversation: " the brown on this swatch card is a little lighter than it is from the paint can ...but you can take this swatch card home for a rough estimate to see if you like it..just remember the paint itself is a a few shades darker IRL."
I don't remember it being this way for a friend of mine, who we helped paint their room a couple weekends ago.)
