I am currently working on one that was 4" inches shorter in width across the bottom that at the top!! Thankfully, it was something that I could cut and square up or I would've just used the fabric for something else later. But since I had to cut off so much from top, I've had to add a much larger border than planned. This resulted in not quite enough fabric and, of course, there is none left. So I've not had to add some corner blocks of another fabric. I'm hoping that all this won't be too busy!!
I'm with you - all fabric will be better measured after it is cut but before I pay for it (especially if grandma at the LQS cuts it). Love that lady - really I do and I'm glad she is able to work some but I'm learning to watch her closely. She overcharged me for a template the other day and undercharged me for a marking pen. Don't think she and the computer at check-out are very friendly yet
But again, I'm glad that she is able to contribute to the family business and she is a wealth of knowledge and ideas!!
