I like this layout. Hanging a gallery wall can be a challenge. A great tip to avoid putting so many unnecessary holes in your wall is to cut out the frame sizes using butcher paper. Attach with painters tape and move them around
have a clothespin with a nail in it. slide the nail on the picture's hook and line up on the wall where you want it. lightly tap the picture so the nail indents the wall. move picture away from the wall, and drive your nail into the indentation!
Attach a binder clip to your night stand to keep your phone charger from falling off. I have a really thick night stand, so I used a small binder clip and attached it to the cord for the lamp. Still works beautifully!
