I got all my hexagons sewn and arranged on my design wall. I am pretty happy with the patterns that emerged and was farily successsful in cascading them down the quilt in a diagonal fashion like I was imagining. Overall, I like the results but the fabric probably isn't ideal for this type of quilt as it has too many small details instead of large multi-shaded shapes.
I realized about half way in that I think I may have bought a ruler that is not ideal. It is flat at the top point so when you sew the 3 pieces together to form half of the hexagon, you have a flat edge (see the photo). Now, how do I match up the rows and make sure the center of my hexagons are lined up and sewn so they meet in the center?? I have the book and looked at online tutorials and I think you use the dog-ears of the points to line up the triangles properly but I don't have any dog-ears at the center point. What should I do?
