We loved the impact that painting a perfect circle had on our spaces, so when we heard about this new project from the paint experts, it was music to our ears!
Perfect for creating a different zones in a multifunctional area, this paint design can be done with supplies you already have, making the most of paint leftover from previous do-it-yourself room makeovers.
Equipment you will need:
- Leftover paint in your chosen paint colours
- Measuring tape
- White chalk
- Scissors
- Masking tape
- Pins
- Paint tray and small paint roller
- Small paint brush (1.5”)
Step 1

First you need to decide on the width of your arch. Here, Clara is going for a 90cm wide arch, about 30cm away from the corner. Once you have an idea of size, mark both ends of where the arch will be.
Step 2

Take the ball of string and cut a piece about the same length as your height.
Step 3

Run the string over the chalk 2-3 times.
Step 4
Tie a knot at one end of the string, at the other end, tie something heavy to give it a bit of weight – you can use the scissors or a set of keys. Get a piece of masking tape and place it just under the knot.
Step 5

Draw it down slightly and ping it, to make a straight mark on the wall. Repeat for the other side of the arch.

Get your masking tape and place a long piece on the outside of each of the lines.
