I started with a 12"x12" quilt sandwich of fabric and batting I had on hand. I was having so much fun, I did another sandwich until my thread ran out.
I found that controlling my speed was difficult at times and that I got the best results when I didn't go too fast or too slow (with my foot pedal and my hand movement).
I used regular sewing thread because it was what I had on hand. I was inspired by the heart shaped leaves so I cut up my smaller sample and made valentines!
