I am posting a couple pictures of how to sew the blocks into rows. There are no long seams in this quilt. My seams were all 3 inches long start to finish. Just remember to do each seam individually starting 1/4 inch inside the edge and stopping 1/4 inch from the edge. This allows the pieces to fit together better. Also, the triangles are the same size on all 3 sides so one side will be ont he straight grain of the fabric. Place the straight grain on the outside edge of the block. It will be much easier to sew the long rows together with the straig of grain on the outside of the blocks.
