These eggs are so different and so beautiful. If you have or can find in a thrift store a bunch of silk ties you could use Fox flats method to dye them.
They pick up the pattern and colors from the ties and turn out so pretty. While you shouldn’t eat these eggs due to toxins in the dye she does say that you can store them afterwards and over time the inside will just dry up.
