Here's a cool tutorial on how to get a tie dyed effect on eggs: https://www.youtube.com/watch?v=lwv3ALtd_jY
I love this more rustic look https://placeofmytaste.com/tie-dye-easter-eggs/
Have fun, however you design yours :)
we always made eggs this way when I was young! Mom added 1 tsp of salad oil (like Mazola) to the cups of dye then swirled it around. dip an egg into one color, then dry off with a paper towel before dipping into another. you can do this with more than two colors if you want!
