{super wonderful nail gun }
{sorry these are left over pieces I dug out , please ignore the cuts}So here it is this is all it is , to transform a doorway into a pretty feature.
I use flat plain primed MDF I use 4 1/2" for the side vertical pieces and 5 1/2" for the header , I then install a nice chair rail to the top of the header and wrap that around , I use a detail piece of jam trim for the bottom of the header , and that is it. Easy Peasy!
