There may be time for this last minute project, if not, you better file it away for next year. I just thought it was so cute! I saw it at Oh Party, via Pinterest. The directions there are very simple, but I added a step.
Eggs get hollowed out. One hole can be a little bigger, you're going to need to slip a note in it. Blow the yoke and other gunk out. I thought maybe I could save the egg insides to cook, but tiny shell scraps and my breath was all over it. To each their own though.
Here's part of what I added: I noticed that the larger hole had a lot of the inside membrane covering it up. It wasn't going to dry like that. I used a tweezer to open that up a little.
Then I decided they were drying too slowly. The eggs need to be dry, thoroughly dry, inside and out. I set my oven for 170 and let them sit inside for a few hours. I added this step because we did a first egg and cracked it opened, just to see how it all worked... the note was wet and gooey. Gross.
Since I was going to paint at least one of these eggs, I covered the smaller hole from blowing with a little white school glue. You couldn't even tell it was there after that dried.
Next, a little note gets written on a slip of paper, rolled up and slipped in the hole. I covered the larger hole with a circle of colored tape. You could use stickers or a dot of hot glue, or whatever. Our notes read something like, "You are egg-stra special!"
Then I did some painting. This egg got to be blue with white dots. The others just got colored circles. I used the eraser end of a pencil for the dots.
This egg got mailed, so I readied a box. I went with a box in a box and lots of foamy paper in between to hopefully cushion it all.
The outside of the box reads, "open."
The inside flap reads, "crack me." I tucked the egg in with some paper Easter grass. Hopefully it will survive the mailing.
edited to add: Here are ours from Easter morning. They opened beautifully. The shells were so dry- they broke nicely.
