It's hard to resist the appeal of Easter eggs!
The way we see it, there's a zillion reasons to make these lovely plaster eggs. As a craft, it's fun for both kids and adults. Plaster is a great replacement for plastic eggs for those looking to go plastic-free (and eliminating the candy-filling issue along the way), they're reusable, they're an ethical choice (vegan/ cruelty-free), and they don't attribute to food waste.
Plaster eggs are beautiful enough for a holiday table centerpiece, yet sturdy enough for an egg hunt. Used in rough form, they work as a homemade sidewalk chalk (bonus for the kiddos!) Alternately they can be finished in handsome detail for a seasonal keepsake to enjoy each Easter season. As a kids' craft, year after year, these eggs become a benchmark of the child's development and creative journey.
And lastly, let's be honest, it's just fun to make a mess sometimes. With this post's help, we hope you're inspired to dive into creating something beautiful this Easter season.
Step 1: Prepare your molds
This step will take some time, but the good news is that the molds are reusable and last a long time. We used ours multiple times and will be saving them again for next year. First step is to find some old plastic eggs in sizes that appeal to you. If you don't have old ones on-hand, ask around or check the thrift store. It's besides the point to go buy new plastic eggs for this craft, please try to up-cycle. And one last tip: make sure you have a drill bit slightly larger than your funnel tip.
- Drill a hole through the bottom (wider base) of each plastic egg
- Use tape to seal all other tiny holes on the mold
- Coat inside of egg generously with petroleum jelly, being careful not to get on the outside
- Click egg shut and reinforce with tape
- Prop them all up in an egg carton. Now you're ready for action.
Step 2: Mix the plaster
Working in small batches, follow the ratio recommended on the instructions (usually 2 parts plaster: 1 part water). Mix in acrylic craft paint for colored plaster. Because the plaster hardens quickly and we were free-mixing colors, we dissolved the paint into the water first before adding the plaster powder. We mixed 1 cup of plaster at a time, this filled approx. 3 small eggs or 1 large/ 1 small egg (depending on spills, and we had a few). Do not rinse plaster down the drain, scrape extra into the trash can.
Step 3: Fill the molds
It helps to have an extra set of hands and a small spatula for this step. Like we said, the mix dries fast, so you must work quickly. Pour small amounts through your funnel at a time. Gently tap mix down into the egg to release bubbles. Top-off as necessary, you want egg filled beyond the brim. If plaster starts to thicken, you may need a chopstick or skewer to work it through the funnel. For two-tone eggs, fill half the mold at a time; tip mold slightly to create a diagonal. What a beautiful mess!
Step 4: Practice your patience
Let the plaster harden in the eggs for at least an hour or two before breaking into the molds. Oh, the anticipation...
Step 5: The big reveal!
Use a towel to twist apart the mold halves to reveal your plaster eggs. If stuck, carefully work the long edge of a knife into the mold crease to break the seal. Do not use the knife tip, and be very careful, your hands may be slippery from the petroleum jelly coating.
Aren't they lovely? If you plan to use the eggs as sidewalk chalk or you especially dig the rough imperfections, this be your stopping point—though the eggs will need a few more hours (an up to a few days, depending on your humidity) to dry completely.
Step 6 (optional): Wet sanding
To smooth the surface of your egg, use a fine to medium-gauge sandpaper, apply a bit of water, and a lot of elbow grease. Wet sanding helps contain the plaster dust, which is hazardous to inhale. Nevertheless, work in a well-ventilated area and have children wear dust masks. Read and head the information on the plaster packaging. Use a gentle touch with the sandpaper, thinking always of the contour of the egg. Use small circular movements around the line created by the mold crease. The last thing you want to do is sand a flat spot onto your egg!
Step 7: Practice more patience
Let dry. Like we mentioned, depending on the humidity in your area, the eggs will need a few more hours, and up to a few days, to dry completely.
Step 8 (optional): Finishing touches
Though we think they're lovely as they are, once the eggs are completely dry, you can decorate them even more by playing around with finishing touches. Ideas worth exploring include: adding decorative detail with paints, glitter, even Sharpie markers. Decoupage or paper mache would be stunning. Hey, add rhinestones, if that's your style. The point of all this work is to create a collection of keepsakes that you look forward to bringing out each Easter season.

Tips and best practices:
Having experimented with this craft a few times, we're happy to share our failures to save you the trouble. Take the time to prep the molds carefully. In our impatience the first time we didn't reinforce the eggs with tape and seal the little holes and we ended up with a big mess. If the petroleum jelly gets on the outside of your mold, no tape to stick to it! It's worth being extra cautious when applying. We tried using food coloring instead of paint—don't do it. The color fades and pools in odd ways. We tried adding glitter both to the wet plaster mix and to the inside of the mold before we poured in the plaster, neither worked—especially if you'll be sanding the eggs.
