The instructions were wrong or poorly written -
The template patterns were not accurate -
The cat "dumped" on it -
The fabric scorched while it was being pressed -
Some pieces were misplaced and can't be found -
The thread was old and now the seams are breaking -
The sewing machine tensions were off and this is why the seams are popping -
A trimming snip ended up being too deep -
Was impatient when removing some stitching and now there are tears in places -
Barely had enough fabric to start with and then made cutting errors -
The cat decided to climb up a quilt that was on the ironing board and now there are tears in it from the cat - and then tears in it from the maker -
It got blood on it from the human -
One of the fabrics from this grouping was used for another project - and a substitute is hard to find -

I think there are more ways - these are just some of the ways I've had issues with a project -

Any additions to the list?
