I matched up the edges and sewed. Fail! So I unstitched and searched for how to overlap the edges. That was a real struggle. I'm still not sure I have the easiest technique out there. I sewed the diamonds together to make rows.
So I feel like I'm on a roll and now it's time to sew the rows together. Screech! Struggle #2! I lined up the seams and sewed. Simple. Right? Wrong! They did not line up. Not even close! So I did some more searching online and found a tip on putting a pin through the seams. I measured 1/4" in from the edge and then put the pin through the seam. It worked! Time consuming. Meticulous. Perfection!
Finished product coming soon! I hope...
UPDATE: Finished it and my friend loved it. She couldn't wait to give it to her husband and gave it to him early.
