If I were to buy an Accuquilt Go die for cutting these hst's, I'd need to get the one that says it finishes at 2 inches, right? Meaning that you sew the two hst's together to get a finished 2 inch square.
It is confusing until you get your head around Finished size not cut size.
Bonnie clearly states :
Triangles will measure 2’’ and finish at 1 1/2’’ in the quilt
Finished size is always the size the piece will be when sewn in a quilt.
I used the Go die number 55319. Waiting for the next clue to see what die I will need to buy if I don't have it. Her last few quilts I could cut all the pieces with Go dies. I think I have all the sizes she uses.
