Step 1: Make your Jesmonite numbers
Firstly, working with Jesmonite is super simple and FUN!
To get concrete-like numbers for your Advent calendar, you’ll need one cup per colour (we used two colours).
Measure the 60 g of powder and 20 g of liquid, enough to fill two number moulds.
Add a few drops of your desired pigment and stir non-stop until you get a smooth consistency.
Pour the Jesmonite mixture into the number moulds and let it set for 30 minutes. Unmould and let it air dry for a bit.
Tip: If you have sensitive skin, wear gloves when handling raw Jesmonite.

Step 2: Create a triangular base
Next, you need to create your base using a plywood board (we measured the middle, 12 in).
With a ruler and pencil, draw two lines to each opposite end in the shape of a triangle.

Step 3: Cut the wood
Attach the wooden board on a worktable with clamps and cut out your triangle with a jigsaw.

Step 4: Sanding
To achieve a smooth look, sand the edges with 220-grit sandpaper and remove the dust.

Step 5: Mark your 24 numbers
To centre the numbers on the finished triangle, divide the triangle into seven rows of 3 inches each and mark them with a pencil. Add masking tape just above the rows as a guide.

Step 6: Drill
Using a drill and a 3/32-inch drill bit, drill 39 holes to fit your 24 numbers.

Step 7: Get ready for the hooks!
Carefully remove the masking tape and start screwing in all the cup hooks.

Step 8: Finish your countdown
You are now ready to decorate your lovely piece, one number at a time, as a perfect countdown to Christmas!
