At one time I had a machine and it hated me... or I hated it, or something. Anyway, it seemed like everything I did on it came out wrong. I ended up frustrated and gave away my machine to a friend, and ultimately gave up quilting altogether for 10 years.
Then I decided to try again, hand piecing this time. I'm still learning. I'm working on my first quilt, a nine patch, but it's for my 14 yo son and he will love it despite (or perhaps because of) the flaws. He loves coming in and watching me piece his blocks and likes laying them all out to look at them together.
I love hand quilting. It's brought me back to a hobby I love.
And - an added bonus - I'm a single mom on a tight budget and if I were machine piecing, I would go through a lot more fabric. I'm able to stick to my budget this way because the fabric that I buy takes longer to sew up. Win-win.
