This shows the three squares in the left row already assembled.
The center square in cards tricks needs to be lined up well where the four different fabrics all meet. When you pin these two triangles together make sure one seam is exactly over the one underneath it. Once all the squares in the row are assembled, then start sewing the three rows together. Remember to pin carefully and sew accurately, especially where any seam is pinned to another seam. Line the seams up well as you pin and you will get nice points.
Assemble each row and then sew the rows together.
Check to make sure your points are sharp as you press after each part is sewn together. If you are not happy with one of the points not looking nice, then pick it out.
