I have some 1x2 project boards for making a frame. The frame will hold a painted sign on Masonite.
I am uncertain the best method for joining the miter cuts and was hoping for suggestions. Wood glue only? Some sort of joiner like biscuits? The 1x2 board are rabbeted with router and =mitered with table saw. It seems to fit alright but there are a few small gaps.
Pictures are below. And some links I read through.
Bonus question: I noticed the 1x2 board can lie flat or tall. Is there a name for these two angles?
