How to spend an absurdly unnecessary amount of time on a project:
Take these chairs:
Gross out at all the goodies under the booster.
Decide to turn the two into a bench.
Trace the seats onto a sheet of mdf and cut them out with a jigsaw.
Take the inside arms off.
Be glad that the seat actually fits back into place and that you didn't accidentally cut the kitchen table with the jigsaw.
Take apart an old body pillow to use for the seat cushion and upholster the seat.
Get nervous that this part of the chair is going to look a little funky cold medina.
Decide that it absolutely looks too funky cold medina.
Rip the fabric off and try and make the torn scraps stretch to cover the original seat.
Put the two chairs on the opposite sides of another chair to give them a faux bench look until you can work up the energy to paint the other arms and put them back on.
