Hanging headboard neatly very close to the wall

Suppose you're a some crazy perfectionist and you're hanging a headboard (or any other similar stuff), first thing you'll notice is that all hardware available at stores when mounted is adding a gap between the headboard and the wall (due to the mere fact that hardware has thickness of it's own). Gap doesn't look good, so here is a quick instructable on how to avoid adding extra thickness.

As always, made at my favorite TechShop (http://www.techshop.ws/) in Menlo Park (where you I hide from family some times).

Step 1: Mark the spots for the hardware first

Here is a cool tip: since the board has a round shaped edge, I couldn't just use a ruler to measure the distance from the edge as the edge is very round and soft (I know, I should have done this before doing the upholstery). So I clamped scrap piece of wood at the 7" mark and pushed it against the edge with equal force at each spot -- the other end of the ruler represented 7" mark. Yeah, you could use one of those fancy ~$40 Incra rulers, but being cheap I haven't bought one.
