What you need:
1 large and three smaller terracotta pots + matching saucers
1 white bowl
Paint and rollers
A 120 x 120 cm sheet of wood (or bigger if you want to go for a dining size)
How to make it:
Draw around the pots on the wood sheet to mark where you want them to be. Saw the holes a couple of centimetres smaller than the circles that you've drawn, otherwise the sheet will not stay in place.
Paint the sheet in the required colour. Also paint the edge on the inside of the sawn circles so that everything you can see is covered.
Use the tape measure to measure the height of the pots. Balance the height of the pots by stacking, or adding one or two saucers.
Fill the pots with potting soil and plant the indoor trees through the holes in the table. Finish the tree table by adding a bowl with potential indoor trees: the Nolinas that you can see here will grow to be large Beaucarneas in time. All together now: 'It's the ciiiircle of life!'
