okay so we have decided on bi-folds, the next problem is frame and please excuse my lack of terminology.
We have cut a hole in the wall, through the plasterboard, leaving the edges a bit uneven, jaggy ect.
We have thought of two options
1. build a frame with 4x2 and add skirting to hide imprefections along wall and top of frame
2.use external angle beads and plaster the walls and ceiling where track will be

What method is best or should we be using and if anyone has links or can explain on the best way to do it that would be great.
