Sew darling! Great start & lovely fabric choices too. Just watched a Fons & Porter I had DVRed a while back & they showed how to use strips to cut your triangles with the long side on the straight of grain. Neat technique. You might check out their website & search that tutorial.Another suggestion was to cut off those "dog ear triangles" that stick out. Helps you line up the pieces much better for joining. Hope this helps. (I had used your method before, two squares, but will try the F&P method on my next project.)
