I fitted some cupboard doors that I made today. I was quite impressed with how they look.
This is a simple set of three MDF doors, hung with kitchen hinges. The doors have lines scored across them that are 3mm deep, painted grey to contrast the white finish, each individual door has one line picked out in a different colour and some of the lines pass through two or three of the doors to tie them together.
What the doors are hiding
I think these look a little bit more like art than simple cupboard doors and I'm pleased with how they came out (I didn't do the painting).
This shows that a low cost material with a bit of time spent on it can give a great finish.
