I enjoyed doing this craft for many years, but moved to mosaic and also to polymer clay. I still have some of the dyes and am waiting for inspiration on how to combine all three types of egg decorating into a single egg. Well, maybe also add a little etching and carving. But these were fairly traditional pysanky.
While they are not particularly inspired, some of the chicken eggs (just from the local grocery) dyed pretty well. My guess is that currently the eggs are so treated, washed and bleached that they would be scarred and non-receptive to the dyes.
