I'm interested in the finishing technique seen in this video at exactly 2:00.
AFAICT he is protecting the panel as he applies stain to the inside edge of the stile, presumably to prevent getting any more stain on the panel.
I assume he stained the panel first so there is a bit of stained panel inside the groove of the rails and stiles, so why didn't he stain the rails and stiles before inserting the panels?
I'll be doing something similar this weekend and I was planning to stain the uprights of this headboard before attaching them to the panel so I don't have to be deal with the inside edges of the uprights once they are attached.
Am I missing something?
