It would be this. Command Picture Hanging Strips. Medium size. They are perfection.
If you are hanging 12x12 Cafe Mount style prints, you need these. See this set of Jeremiah 29:11 prints? I hung them up in less than a minute! But then again, I have experience hanging 12x12 Cafe Mount prints. It would take you at least 2 minutes. And they even look straight.
So I simply took removed them from the wall in the living room and put them above the bed. No nail holes. No crazy level that I can never get the liquid part quite in the middle, no heavy hammer to lug around.
Sooo easy. Try them! See what you think:)
And as a completely unrelated side note, clearly I am in the market for pillows. The big yellow ones are staying. All the others need to move on. Suggestions?
