Built in liquor cabinet
I am looking to build a built in, between the studs open shelf rack for bottles behind my bar. I am planning to remove about 48" of one of the studs to connect two stud bays and making the cabinet span across the now open two stud bays, so it would measure 48"x48" recessed into the wall between the studs. My question is, can I use solid wood to frame the sides, top and bottom and then plywood for the back? I want to use the solid wood for side panels because some of the edges will show, but I also know that is seems that solid wood is more reactive to humidity changes than plywood. I want to make sure it will not warp. Thanks for any help or advice!
