i've been quilting for almost 8 years and it is my only source of income.
i haven't made one quilt that i haven't wanted to kick into the backyard and burn in the fire pit.
this is a common emotion with many quilters - we know the vision we've had in our head on how the piece should look and since fabric and quilting stitches are a fluid media its prone to mistakes, errors, etc.
as much as we see ever mistake in our work the general public doesn't and they think it looks amazing.
i'm sure the people in your life love your work and want you to continue - it does get better over time.
i hope some day to produce a piece i don't want to burn but i really don't believe that will ever happen for me but it certainly won't stop me from trying.
