What you need:
- A cactus (the photo shows an Opuntia)
- Various colours of Lego bricks
- Sturdy plastic bag
- Wood panel for the base
- Gloves
How to make it:
Step 1:
Measure the cactus's pot (the pot size is often shown underneath) and take that as the starting point for the pot that you're going to build. It can be a tight fit: the cactus grows slowly. Saw a square in the size of your design, and build the decorative pot on this in different coloured layers.
Step 2:
Hang the plastic bag over the last but one row of bricks, and secure it with the last row. If you like things to be firmly secured, glue the bottom to the wooden square.
Step 3:
Remove the plant from the plastic pot, place it in the decorative pot and top up with cactus soil. If you don't have any cactus soil to hand, mix 2 parts sand with 1 part potting soil: cacti don't like soil that retains too much moisture. Give the cactus and its cheerful pot a bit of space to bring out the effect of the combination.
