Since I decided to accept results that didn't quite turn out the way I wanted (as long as a star shape is recognisable a star has been made...), today's star is a little messed up - but it was a lot of fun to make:
on white paper
on the window
And here's how I made it:
Glue crayons to a piece of cardboard and hang them above a sheet of paper that has been attached to some solid background so it can be propped up against tha wall. Cover parts of the paper with painters tape if you want a shape to remain white. (Here's a problem, though: Once the paper becomes oily from the wax it's very difficult to get the tape back off. I ripped a hole in my star and some of the tape's glue remained. I'm still searching for a better solution...) And then...
Yes, that is a blow-drier in the bottom left corner. Just turn it on and keep pointing it at the crayons and the wax when it starts running down. (Beware of spatters!)
P.S.: My dad just emailed me a photo of a cactus star he and mum found today on Lanzarote, and I think it's really beautiful, so this will go in here, too:
