Thanks, I posted it as a new discussion on the group page. I already have pebeo setacolour paints and will try this project with those. They may not be as vibrant as the ones Lea uses, so I'll have to see.
Lea said not, but I'm skeptical myself! Wish it were easier to understand the organization of the website. I could not find this discussion and had to go back to the email to click on your question!
