I didn't want to ruin my kitchen tiles and wall by drilling a giant hole through it, but I did want to hang my knife and paper/foil thing to the wall. Solution: superglue and magnets.
Step 1: Stuff You Need.
*magnets (I got 250 rare earth magnets on Ebay quite cheap. diameter 0.5mm/0.25 inch but you might want slightly larger ones)
*stuff to put on your wall.
