Hi,
I need a bifold cupboard door, and to match the others it has to be a flush ply door.
Only one place makes these, to order, and they're £160.
Do you think they attach two narrow door blanks together?
I've just noticed that one place has 381mm blanks.
I could pay a chippy to do this but it would be £112 for the doors, plus hardware, so not much left for his labour cost.
Any info/advice?
Cheers.
