Easter Eggs......"the old way?"

We are celebrating in a rather non-traditional way this year.......instead of Easter (i know it was like 2 weeks ago), we are celebrating the Spring Equinox (also forever ago, i know).  Calender's syncing up, though, right?  I'm going to try and decorate some eggs using leaves and flowers as pressed stencils and use foods in boiling water to color them.  A video of how to do it was posted to my Facebook feed and I got dared.  My kids are excited about it.  Anyone ever do this?  Tips?  Stories?
