Before & After porch columns. I love how the stone not only updates but with the white covered pillars, gives a relaxed look rather than a shack look. (You don't even really notice the dumpster dive rocking chair in the after pic.)

I am not a carpenter and this was my first attempt....you may want to put some slots in the solid wood panel under your bed. This will reduce the chances of your mattress going mouldy. Or just air your mattress outside occasional. I work in a bed shop and mouldy mattresses can happen quite quickly with moisture and heat.
