I had the most amazing afternoon decorating eggs, it's been a while since I've done some art/crafting but every moment was amazing !
I know it's a little late, Easter has passed but maybe it'll give you some inspiration for next year, and on the positive side you'll have some time to scout for nice paper napkins or tissue paper. The issue I've had was trying to find paper napkins, I looked everywhere but nothing was suitable so finally I stumbled on this set and it had enough variety to make a few eggs to showcase.
To begin: Hard boil your eggs, set them in a saucepan covered with cool water and a pinch of salt. Bring the water to a boil and immediately cover and set aside for 10 minutes.
Drain, soak in cold water and then drain and put them in the fridge, this can be done the day ahead.
Start by cutting out all the shapes you'd like to use from your napkin(s) and set aside.
You could skip the dying and go straight to decorating with the napkin, but I happened to have some dye already mixed in mason jars so I used and combined both the napkin art with the dyed egg, I'm pleased with the result.
To stick the napkin to your egg you just need the white of 1 or 2 eggs, whisk it with a fork until it loosens up and looks a bit frothy. Now with a dyed (and dried) or undyed egg simply brush the egg with a little bit of egg white and stick your napkin to the egg gently, smooth it but don't fuss with it too much. Start brushing (or dabbing with finger - sponges work well too) using more egg white to seal the napkin to the egg like a varnish.
Once it's stuck, set it aside somewhere to dry, it'll take about 30 minutes to an hour. They're ready when the surface is very dry (it's ok if some clear bits flake off) but it shouldn't be moist at all.
If the napkin looks a little lumpy don't worry because as it dries it sticks to the egg, but don't make the pattern too lumpy by overlaping/pleating it.
I hope you give this a try because not only is it super easy but it's fun and you end up with some super elaborate looking decorated eggs with very little effort (no painting or anything!)
