I mount templates on light cardboard (available at craft stores) use a small 1/8 inch punch on all corners to mark on the back of all fabric used. The 1/4 seam allowance corners on all sides to the template. You do not want to sew pass these dots, especially on Beauty. Laura has provided tips on the right way to assemble each block in her pony book.
A good friend of mine draws with Gel Pens on the back of every fabric piece, reproducing the 1/4 seam line, and uses this in hand quilting. Again, not going pass that connection dot in the corner. I hope this helps you. Good luck; try, try again, and you will get it done and learn more by doing it.
