After a month or two of psyching myself up for hanging, the headboard has finally been hung in the master bedroom. Credits:
Valley Forge - pleather
Stupid Amazon store - nailheads that ended up in three bandaged fingers
OOK - hanging cleats (remains to be seen how we feel about these)
Home Depot - wood, screws, brackets etc (in total 75 lbs on the wall)
Joanne Fabrics - batting, foam etc
Davis parents - lovely paint job that contrasts nicely with the white headboard
Lesson Learned: you can probaby purchase a similar headboard or have one made for just a tad more and save your fingers, time, weight, and end up with something a little more professional looking. And if you do decide to do it yourself, use a straightedge!
