If you ask my DH, I sew too slowly. I won't let it sew over the mid-speed to preserve my machine normally. Going too fast is hard on the machine parts & I don't want to wear it out prematurely. Sometimes though, even I get a little anxious. Just once with my present machine I was exhausted & ready for bed, so I jacked it up & stomped on it. Finished that long seam quickly, but DH couldn't stop talking about it for a month!! LOl!
