Summer means camping and camp fires, and working on those outdoor projects around the house. If you have some left over materials why not make a simple two board 'Viking chair'
I made this one a few years ago. I kept it in the truck and would take it with me to sit and watch my son's baseball games. I made mine out of some 2" x 8" construction grade spruce I had, but you can make it lighter. All you need is a saw and a drill to drill out the mortise. You can clean out the mortise with a chisel if you like, or just cut the mating board to fit. I added some foam rubber for comfort.
I drilled a shallow hole in the back of mine and attached a bottle opener that I purchased from Rockler woodworking and hardware.
All I have to do is reach behind me, open, and enjoy a nice beverage on a hot sunny day. Ahhhhhhh
Enjoy the fruits of your labor.
As always - Thanks for following
Be safe and be creative
Best
