Help! I am trying to follow a pattern that uses 60 degree triangles (6 of them) that shape into a hexagon. Bought the triangle with the one "flat" point. Don't know how to join the triangles. Should the "flat" tops meet. Supposedly, when joined, the point of the middle triangle will drop down between the triangles to the right and to the left, so as not to get into the 1/4" seam. Tired of ripping out the triangle again!!!
