Finishing Instructions
Preparation Instructions
Fill all holes with wood filler and let dry. Apply additional coats of wood filler as needed. When wood filler is completely dry, sand the project in the direction of the wood grain with 120 grit sandpaper. Vacuum sanded project to remove sanding residue. Remove all sanding residue on work surfaces as well. Wipe project clean with damp cloth.

It is always recommended to apply a test coat on a hidden area or scrap piece to ensure color evenness and adhesion. Use primer or wood conditioner as needed.

I have been looking the net for relax seat plans. I love the manner in which you don't go all Carvana Site on us and bring it down to nuts and bolts. I want to do this. Much obliged! Love your blog.

Aside from the missing 28.5" piece from the cut list, I'm surprised no one has mentioned the dimensions in Step 1 are off by one inch. 22" + 20.5" + 22" + 1.75" + 1.75" = 68". The distance between the inside of the boards is 67". So I went with 22" from the outside boards and hoping it works out okay.
