It’s hard to line up a framed photo or piece of art perfectly on the wall. An easy, fool-proof way is to tape a thumbtack (pointy side out) directly under the frame’s mounting bracket. Now, position the frame where you want it to hang and press just hard enough so the thumbtack’s point makes an indentation. You will have a perfectly marked target to position your nail. Remove the thumbtack. Now your picture will hang perfectly!
