I am making a crumb quilt and want to set my squares on point. There is a lot of help out there for figuring the corner and side triangles, but I also want to add sashing. One site said to add the width of the sashing into the block... ok I may be pretty dense here.... there is sashing on each side of the block. Do I add each side or only one? Any help any of you can give me will be greatly appreciated. Quilter1234
