They were about 4 1/2 wide and 2 3/16 tall. The width was adjusted so as not to clip the wings on the inside. You can see the full write up on the segmented form page with the same name.
This was actually my second set of eagles as I was not completely happy with the first set. A few to many misalignments.
Thanks for the info.
The one I tried was much smaller. SL of under 2". Way to small. Any off cut only compounded the issue. Someday, I may try again. I do like the pattern.
