I have always had trouble making picture frames and hate them.
My DIL asked me to make a frame for my son's MA diploma. I made him one out of brown oak for his BA and she wanted one to match. Well, I can't get any brown oak and figured trying to match it would be a fool's errand, so I made it out of red oak, figuring they would go together because they had the same grain, but were obviously different woods. The first one was matted maroon (BC) and this one will be matted red (UW), so it seemed appropriate.
I spent some time to make sure my kapex was perfectly adjusted, both vertically and horizontally. I cut my pieces and they are 45* dead on. I put them together and there is a space on the inside of all the corners big enough to slide a sheet of paper in. A little filler and no one will ever notice it, but WHY?!?!?!
What could I possible be doing wrong?
