Your Cathedral is lovely! You are doing a fabulous job!
These blocks get easier to do the further you go.
I am improving on my ability to shape the "windows" as I go---and so will you!
Is your quilt black & white or have you shown it to us in black & white scale?
You said you had a long way to go? Think how far you had to go when you started this! You are well underway!
Remember the old saying---"The journey of a million miles begins with the first step"? :wink:
