DIY Cement Brooches

Industrial-meets-feminine in this chic, modern cement brooch project!

What you need

Makes 4 brooches (1.5" diameter)
-cardboard or thin plastic containers with a flat bottom, to use as molds
-sharp scissors or utility knife
-plastic wrap
-masking or painters' tape
-bag of cement
-small plastic tubs and at least two plastic spoons
-wood stirring stick
-fine grit sandpaper (180 or finer)
-super glue or epoxy
-brooch pins
-paint, lace, stencils, or other objects to embellish the finished brooches

Instructions

1. First, ready your molds. I used cardboard tins of salt and pepper for mine because they were cheap, a decent size, and easy to cut (important for unmolding at the end). By cutting each tin in half, I was able to make two brooches per tin. In a completely unrelated note, is anyone in need of a lot of salt and pepper? 2. Set aside the two cardboard halves with tin on the bottom. Take the other two halves and pop the shaker tops out of the cardboard tubes. We will replace the dispenser pieces with a smooth surface, so that your finished brooch is not shaped like a salt and pepper shaker. To do this, wrap the exposed bottom in plastic wrap, pull it tight, and tape it to the tube. 3. Seal up the bottom with masking or painters’ tape so that no cement leaks out. Now you have a flat bottom for the mold. 4. Now it’s time to set everything up to mix and pour the cement. I did not use quick-drying cement, but since the brooches are small they still firmed up within 15 minutes. You’ll want to get all the supplies ready to go BEFORE mixing the cement. *Note: The chemicals in cement are activated by water, so in the next steps, use two separate spoons—a “wet” spoon and a “dry” spoon! 5. Use a plastic spoon to transfer roughly 1/2 cup of dry cement powder into a plastic tub (an empty margarine tub works well). 6. Use a second spoon to begin adding water to the tub of cement, one spoonful at a time. Stir well with a wooden stick. 7. Continue to add more water, one spoonful at a time, and stir. The quantity of water needed will vary based on the cement you are using. You are looking for a consistency like a biscuit dough—it should be pasty and wet-looking, but shouldn’t drip off the stir stick when you hold it up. 8. Once the cement is well-mixed and there is no dry powder visible, transfer a dollop into one of the molds. Gently tap the mold on the table and shake it from side to side a bit, in order to settle all the cement to the bottom and get out air bubbles. The cement should be roughly 1/8″ to 1/4″ deep, but no deeper—or else the brooch will end up too heavy. Repeat for each mold. 9. AND now we wait. Isn’t that always the hardest part of a DIY project? My brooches took two days to dry completely. You can peek before that if you want by cutting a mold open, but be careful not to break the cement disk! 10. When the cement has fully dried, cut away the cardboard tubes and unmold the brooches. Gently sand each brooch to smooth out any big uneven parts. Or leave as-is, if that’s your thing. 11. Attach a brooch pin to the back of each piece using super glue or epoxy. And there you have it! All that’s left is decorating. I used lace ribbon, a tree stencil and paint, and gold paint to transform my brooches. These DIY cement brooches make great accessories to pin onto your blouse or a handbag!
