I finished this a while back but learned how to use glue stick on the seams and so pleased all my seams matched. For so many seams, it was amazing. Since then I have shown others. SO easy. Less pins to stick me to while I sew. You use a dab of glue on each seam, then add the piece to sew together and press down the seams on that one to match the glued one. And it manages to work in the "slight" extra fabric so it matches. I love this technique, learned in the class.
