This is my favourite kind of project — high impact, low budget, low effort, easily changeable. I already had the black tape on hand, but if even if you had to buy tape your maximum spend is about $10 to $12. I took me 15 minutes to complete. No measuring. Just go for it. Now I’m thinking of painting a few of the resulting triangles in bright yellow…

Materials

• washi tape (or you can use electrical tape)
• scissors

How to make it

Step 1: Apply tape in desired pattern. Done!
