One question though: Did you assemble it in diagonal rows?[/QUOTE]
No, I assembled the rows straight across. I imagine the MSQC wedge is very similar to the ruler I used-there will be a flat edge along the top of the triangles-makes it easy to line up the wedges correctly, and when you press them open, they form a straight line across the tops and bottoms.
Congrats on gaining a son, and your quilt will be beautiful-looking forward to seeing it!
