I tried to google that quilt name and nothing that I could make heads or tails of came up.
I am glad you are making progress in getting a good result. i have to be honest, reading there is an inch and half difference is a big difference and makes me think more of what could have been done better in the construction part. To continue to cut off makes me wonder if things will go together well down the road. So be careful!
It is so important to cut and sew accurately..
can't wait to see the final project.
