A frugal solution…
Call Benjamin Moore. They will send you for FREE (I love FREE) larger paint chips (8 x 8). You can order as many as you like of as many colors as you like. You can then tape the 8x8 samples of the same color together and tape that to the wall. Much easier and FREE!!! They didn’t even charge me for shipping!
This is the direct # for Benjamin Moore paint chips: 1-888-854-9889.
I called and requested 4 samples each of 10 different colors. They said it will go in the mail today…I should have them in 3-5 business days."
