Start your indoor garden with this new Fall For DIY project

We’ve got another project for you from the awesome maker blog Fall for DIY

Last time, Fran made a gift-worthy set of soaps using the FormBox and a potato. Today, she’s using concrete and a dipping bowl to make a domed concrete planter - great for decorating your windowsill or starting up a mini garden.

What You’ll Need

Mayku FormBox

2x Sheets of 0.5mm H.I.P.S.

Small dipping bowl

Cement powder

Cement dye (Fran’s used black)

Stirring sticks

Plastic cup

Vaseline or Baby Oil

Fine sandpaper

How to Make

1. First, you’ll make the mold for your planter’s base. Fran’s chosen a black H.I.P.S. sheet, but you can use any color you fancy. Place the dipping bowl upside down on the bed of your FormBox and form it using a sheet of H.I.P.S. Check your FormBox manual if you need a reminder on how to form. 

Next, you’ll make the dome for your planter. Fran used a clear Mayku Sheet for this one so she can admire her plants growing! Form your dipping bowl again using your second sheet of H.I.P.S. You can put this form to one side for now.

3. Mix up some concrete using two cups of cement powder. Slowly add small amounts of water and keep stirring until you’ve got a smooth, thick consistency.

4. Pour the concrete into your planter’s base mold. Fill the mold about halfway up.

5. Mix two teaspoons of your chosen dye into the remaining concrete. Pour the dyed concrete into the mold until it’s about three-quarters full.

6. Cover the outer bottom half of the plastic cup in Vaseline or Baby Oil. Keeping it centered, carefully push the cup in your concrete-filled mold until the concrete fills the mold to the top. Leave to set for about 48 hours.

7. Grab the dome you formed earlier and carefully cut it out around the base. Then, cut a hole in the top so your plants can peak out. Lightly sand the edges of the dome so it’s totally finger-safe.

8. Once the concrete is completely dry, remove the cup and gently push the concrete out of the mold. Sand down any sharp edges and smooth the surface. Now you can pop in your plants and place your dome over the top! Ta-da!

There are lots of different ways to use concrete in your making - what do you have in mind?
