4 sheets of thick acrylic what to do?
All the advice in here is great if you have more money than time. But transporting one sheet of this monster to a store and getting two panels cut will cost next to nothing. Show up with four huge panels and start asking them to prep it all and it will get expensive.
Don't be a "do-nothing DIYer" (I did it all myself! With a kit from the store!), with like five minutes if you tubing and several hours of careful work. Nobody ever forum argued their project finished.
