Materials + Supplies:
• Water Proof Fabric (something that won't absorb water)
• Plastic Bowl
• Diamond Hand Polishing Pads / Sandpaper / File
Size: 18" x 18" x 8" high
On a piece of fabric, roll out ShapeCrete to a uniform thickness (3/8"). Wait 10 minutes and then drape the fabric into a bowl. Smooth any cracked edges and allow to cure overnight.
STEP 1: Cut the Fabric
Trace out a large circle onto the fabric. Leave some tabs on the sides so you can lift the fabric up to drape it into the bowl later.
STEP 2: Bowl Details
The shape of the bowl will change the way the fabric folds. Test fit the fabric into a few different bowls to get an idea of what will happen.
STEP 3: Mix and Pack ShapeCrete
Mix ShapeCrete to a Clay-Like Consistency. Pack it onto the fabric, flattening it out as you go. Smooth it to the edge of the of the fabric to a thickness of about 3/8" - 1/2".
STEP 4: Smooth and Let it Set
Take a bit of time to smooth the mix out. This will be visible as the inside of the planter. When you're finished, let the mix set up for about 5-10 minutes. This time will vary depending on the temperature and humidity where you're working. To check the mix, lift up a corner of the fabric. If it slumps down, it's still too wet. If it cracks, you've waited a bit too long and should put the piece in the bowl right away.
STEP 5: Drape into Bowl
If you have a small piece, you can do this yourself. For larger pieces, it's much easier with a helper. Lift up on the tabs and gently drop the piece into the bowl. Let the edges fold naturally.
STEP 6: Smooth any Cracks
Smooth out any cracks that may have formed in the tighter bends and clean up the inside of the planter by removing any loose material.
STEP 7: Cover and Cure
Cover the piece with plastic and allow it to cure for at least 24 hours.
STEP 8: Remove Fabric
Gently pull the fabric away from the planter, being especially careful in the tight bends.
The fabric can be cleaned up and used again.
