I am trying to turn the corner with the 3 sections of sashing/blocks visible on the right hand side. Is there someplace to get directions for this plan? Can someone offer some suggestions as to how to get the 3 sections to turn the corner? Eventually, there will be the same 3 sections on the left side of this. I don't mind having to cut a block in the center knowing that that may be the only possible way to turn the corner, but I need some system of doing it as I must make about 10 of these turns. HELP!! or am I just crazy to attempt this? Thanks for any & all help.
