What I learnt from craftsman this time was how I have to design fitting such as doors and the points how the doors are closed . As we can see from above photographs. I ordered white melamine board inside of the furniture. because of it, you can slightly see the white line from the front even when the door are closed. The craftsman noticed the “not a beautiful point” and let me know about it and this is why I visited to the factory today.
Very tiny matter and may be no one will notice it, but I believe this, I call it “noise”, may cause a uncool design overall when noises happens a lot. So my job is to get rid of noise as much as I can to make beautiful furniture !!
