I am my best critic
In the case of quilting -
Why? How?
Because no one else cares about the result as much as I do.
Because I learn from my mistakes.
Because - at this point in my life - I still hope to get better and learn new techniques and improve how I do old ones.
Because I want to make things that I will be proud of.
Because, after going through a learning curve to learn a new technique, it frequently takes much less time to do the process "right" the first time than to unsew and redo.
Because I want my items to be able to withstand the scrutiny of my Mom (even though she is no longer living)
By the way, Mom did not expect or demand "perfection." She did, however, encourage doing the very best one could!
