I've bought several large wooden frames with glass front to put my A3+ photos printed on fineart papers, the frames I bought were larger than A3+ intentionally bought that way so I can create my own borders.
I wanted to make my own border some frames I want white borders and some frames I wanted black to create the effect I wanted.
My question is where do I get the material? and what is the best material to use? my guess the white border would be most critical as I didn't want the border to turn yellowish and worst still stained after a while.
Thanks in advance or the help and pointers on where to get and what to use.
