That sounds like an excellent idea and shellac would make the surface durable. (Show pictures!)
I'm working on finishing projects I started over the winter: I still have that crochet sampler afghan to finish, the lace shawl I started so long ago I'm not sure when, a vest I started last month (but need another set of needles to continue working on) and a pair of socks that I started eons ago. I've been working on the socks this week. I have 11 more rounds on the leg. (It's lace AND cables and I feel crazy for attempting it.)
Krylon's paint for plastic is wonderful stuff. I'd think for decoupage that using the Krylon paint or at least starting with the primer for plastic would work. I've used it to turn large, cheap, orange plastic pots from Big Lots into gunmetal-colored pots that are much less hard on the eye and to spiff up some faded plastic shelves I was using outside for plants.
Interrupting the craft discussion to say...
Happy Birthday Allyson!
HAPPY BIRTHDAY ALLYSON!!!
Happy Birthday, Allyson! I hope you have a great day!
Happy Birthday!
And ooh, I forgot about Krylon. Okay, I have some options now. Need to figure out design-wise what I want them to look like in the end.
