Have now set up some kitchen cabinets at an angle in a corner (the angle is of course not 90 degrees, rather 91-92 degrees). Now there should be filler pieces both above the cabinets up to the ceiling, plinths, and filler pieces in the "corner," and maybe on the underside of the wall cabinets too.
Is there any nice system with plastic strips to cover and hold together the joints, or how do you handle the corners? Saw from the back and hope the seam turns out well?
