… that I learned the hard way
I had a great sewing teacher - my grandfather. When I was 10 or 11 - he taught me how to draft patterns and use the old Singer sewing machine that no one else in the house ever used. He expected me to keep at it until I got it right. There was no "quit" there was "get it done". We made drapes, recovered chairs, and made all kinds of useful things.
What he didn't know how to teach me was perfect piecing when it came to quilting. I didn't see this as a problem. it was just something I needed to figure out.
