Making changes/corections - - -
I know that I am usually in the "change it if it seems to be wrong to you" group -
However - there are times when leaving it be might be the better way to go.
Examples:
If one has no more of the "perfect" fabric - and there is a chance of making it worse instead of better.
If the piece was made by someone near and dear to you - or that was someone's best at the time. Memories are more precious than perfection.
Sometimes the anomaly does make the piece more interesting in a good way.
If the quilt is for hard use such as a car quilt or kids' tents - finished is much better than perfect.
I still think things such open seams, or 1/16 inch seam allowances should be fixed.
