Head to Playatech.com and choose your favorite design. I started with the Playa Love Seat. Plans for any of the furniture can be downloaded for $5. Proceeds go straight to the Black Rock Arts Foundation, helping artists from around the world get funding for their artwork. Snazzy!

You'll get an email with a .PDF blueprint of your bench or chair. I made this one from 3/4" plywood and it's still just a bit rickety, so I'd recommend going with at least 3/4" or possibly 1", though the plans specify 1/2".

 If you chose the Love Seat, you'll have two side supports, a back support and a seat, and a couple of support pieces for underneath.

I used an .svg file of a monarch butterfly for the design. I like the butterfly shape because it makes a great selfie bench: the size works out so that it really looks like someone sitting in the center of the bench has grown glowing butterfly wings. A dragonfly design might work well, or a logo or camp mascot. Just be sure your design doesn't have any "floating" pieces that will be disconnected when they're cut out. 

Also, removing a whole lot of the plywood material definitely compromises the integrity of the bench. I'd planned to cut the outer butterfly shape as well, but ended up leaving the edges intact for strength. 

Remember, people will be leaning back on the cut-out section so be sure your design doesn't have too many thin, breakable areas. 

This svg file has cutouts between the top and bottom wings. I cut this on one side but then realized that it really compromised the strength of the bench to have the top wing "floating" and just connected by a few tiny spars to the body. I ended up patching & filling the cut and leaving both the top and bottom wings as one piece.

Next, I went to Midjourney and imagined some designs. I absolutely loved the classy black and orange color scheme and simplicity of the Midjourney imaginings. I ended up taking a lot of inspiration from the overall feel, but also made a lot of changes and really made the design my own.
