What I used:
Chairs: Kijiji $10.00 for both
Stools: Value Village 3.99 each
Spray Paint: Michaels $6.77 per can x 5
Total Cost: $51.83
I used Krylon Lacquer Special Purpose Spray Paint. I love the glossy finish that it leaves and it dries super fast! I sprayed my chairs and the stools with 2 coats each. Remember to let each coat dry before applying the next one. This can get messy so I would recommend using a plastic drop cloth.
It's as easy as that. Good luck with your project and remember to have fun!
