You nailed it with the WallMarker

Can we level with you? Holes are not a good look on your wall. If you're spacially challenged when trying to hang artwork, check out this $3 gadget, which eliminates the guesswork of where the nail should go.

The WallMarker is a piece of chalk that's shaped like an arrow. Stick the adhesive side of it onto your picture, press it against the wall where you want it, then remove the picture and voila!, there's an arrow pointing to exactly where the nail should go.

If you make a mistake, wipe off the chalk and try again; the marker works several times. Buy it at wallmarker.net. )
