If you're wondering how people decorate fully intact eggshells and/or use them as decor, first you need to know how to blow out an egg! Blown eggs are beautiful for natural home decor or countless DIY projects.
Shake your eggs carefully to scramble the insides so it is easier to blow out.
Very gently poke a small hole in the top and bottom of your egg. Be careful not to apply too much pressure with the needle and your fingers on the sides as you may crack the egg!
Over your empty bowl, blow on the top hole of your egg to push out all the insides.
Place your eggs in the bowl of hot water right after you blow them. Hold each one under for a second to get water inside of it. I used a small plate as a weight to hold them under. Allow them to sit for 10 minutes.
Place your tea towel over your open egg carton. Press a small divet in the towel in each compartment for the eggs to go into. Place your eggs in each spot.
Allow them to dry for 24 hours.
Coat the eggs with Mod Podge. (See notes if you want to dye them!)
Allow your blown eggs to dry completely. Repeat the sealing process 2-3 times.
Notes
Be sure to shake your eggs before poking any holes! This will scramble up the yolk so it doesn't crack your egg on the way out.
When poking holes in the eggs, be very gentle. You can carefully move your needle in a circular motion to make the hole slightly larger. Work slowly and don't apply too much pressure between your fingers or your egg may break!
Let your eggs sit for 24 hours to fully dry before coating them with Mod Podge so you are sure there isn't any moisture left inside.
You may choose to do 2-4 coats of sealant on your eggs to ensure they are a little bit stronger. Goose eggs may only need one coat since they are already thicker to begin with. Do whatever makes you feel best!
If you plan on dying your eggs: dye them BEFORE you coat them with Mod Podge!
