how did u attach the headboard to your bed? did u buy brackets for it? were they a certain type?
My (reasonably old school) metal bed frame has holes in the end of it for attaching a headboard. So when I was making this one, I measured the distance from the floor to the hole and from one hole to another and drilled corresponding holes in the MDF. The holes in the frame were conveniently 1/4", so I just got bolts, nuts and washers to use for that size hole
