I mill everything myself. I buy the 7/8" x 9 3/4" planks at my local mill, anything from 8 to 16 footers. The price just increased to 54 cents from 50 a foot.
I first cut into the 2 lengths I need, then cut rabbet joint on 3 sides of the shorter "end" pieces (the third is the frame rest) and then glue and screw. Once done that I cut in my hand holds using a moulding head cutter, takes a few seconds per hand hold. A quick sand and that's it.
Then I pass off the painting (I hate painting).
