Here are the instructions:
1) Spray-paint the pots in a well-ventilated area (I did two layers of Rustoleum's "Flat White")
2) Paint details (I mostly used acrylic paint and a thin brush)
3) Spray a light top coat of varnish to give the pots a protective layer
I used acrylic paint to paint the inside rims and pot edges in a light mint green colour. For the black triangles and other details I used a permanent marker. For the gold dots on the polka-dot pot, I actually used gold spray paint (I sprayed a little patch of the paint onto an old piece of cardboard, and created the perfect dots using the back of my brush).
This DIY is super easy and really changes the look of those standard pots. Oh and I also took a few photos at the end of a new birch panel painting I made. Hope you like it!
