Putting it away for a little while might just work. Then while you are waiting look at some different patterns using triangles. Some are really easy and don't involve Y seams but you just plan your work ahead and then sew the triangles, alternating them [one point up/base down and the next point down/base up.]
I know I had some patterns using only triangles but can't find them right now. Darn it.
Maybe someone else can post to this.
