While you’re dying the eggs with liquid dyes, you can safely let your kid have fun with wax pastels. The eggs for this technique should be warm but not hot 🙂 The heat makes the pastels softer and really very nice to work with. It is a little messy but it’s well worth it. You can scrape a little pastel on the eggs for raised patterns.
I saw this technique here and really liked it (I don’t know whether the wax pastels are particularly safe but the eggs are certainly splendid). To make the bowl, I cut in two one of the ornaments I made this winter 🙂
