I made this pochade box myself from scrap pieces of wood, no electric tools were used. The easel part (the top) was inspired by Jim Serret, plein air painter, how to make your own. This is a "standard" size box, measures 12" x 16", 2 1/2" deep (box). The tray on the side (brush holder) measures 11"x 4 1/2". The mixing palette is made of clear plexi glass with the adhesive paper protective still on the back (the largest piece I had) measures 15 1/8" x 10 7/8" x 1/8" thick. The box weighs 2lbs, made from 3/8" Maple plywood for the sides for top and bottom including the dividers. The top and bottom panels are made of Laune. I was also inspired by @Kaustav
and his posts. In the very beginning this appeared impossible, out of reach for me, but as I looked around more carefully at what I had on hand, which is not much at all but I am skilled, everything started to come together ridiculously easy yet very unexpected. The only things I needed to purchase were the brass hinges on the back (not shown), the finish (Spar Urethane, quick dry, indoor/outdoor) for it with brushes for the job, bungee cords, just enough of everything nothing more at all. It is built for outdoor use, to handle Canadian weather, is harsh on things. The handle has enough room to be wearing a pair of gloves/mittens to carry when cold. I have the freedom to paint sketches/paintings measuring from 5" x 7" (horizontal) up to 12" x 16" , on both horizontal/vertical. This will sit on my lap most often, I need a strap to put around my waist and attach to box to better secure while painting and resist weather (winds). Need a stool and new supply of paint and to mess up this box some by using it. Thanks for looking, enjoy!....now back to painting!
