I finished my prototype armrest/cupholder/misc tray project. I bought just the framework from a seller on here. I added 5.25" to the length, built up the foam with 1 1/2" upholstery foam then I drilld out the cupholder holes in the plywood. I made a pattern and had my mom sew the the cover up. I picked out this fabric because it's temporary until I get the seat recovered and I like cats. I figured if it wasn't going to match the current interior it should stand out lol
