It looks great in the photo.
Have you heard about the Jane A. Stickle quilt that was written about in the "Dear Jane" book - that many of us are trying to emulate.
Overall, the quilt looks great - breathtaking - but look closely at the pictures - many of the points don't match, joins are wonky, edges are uneven - in some ways her work is a technical masterpiece - but in other places - oh, my - her blocks are of different sizes and compensated for by sashing -
So - your points may be 1/16 of an inch off - I can relate - but if you can't see the glitches from six feet away (or more) - don't worry about it.
As far as time and expense goes - I can also relate to that - but if you had spent that same amount of money traveling or on a vacation - what do you have left? The memories - (and maybe some unpaid bills).
But if you don't like it, you don't like it. I've bought clothes that I thought I liked, and then later wondered what was I thinking.
