I'm not even sure how to ask this question.
I'm doing the 2015 BOM here and loving it. It will come out 36x48 and I need 36x66 for my window. I'd like to sash to give each block it's own space. How do I pull this off? And how much material would I need for the sashing. And would all the sashing need to be the same material?
I feel so stupid.
