That's funny.....my husband is always telling me to speed it up. LOL Anytime we go shopping or to a sporting event I have to almost run to keep up with him. He just can't understand that I am short with short legs and my stride is NOT as long as his.
As far as sewing too fast. That used to be me too...always in a hurry to see the finished project. I've slowed down considerably; and if I don't quite understand something I don't just go ahead and hope for the best. I'll read the instructions many times and if I still don't understand then I will start searching online. The worst feeling is when you complete your project and it looks horrible. It gets stuffed in a bag and put away in the closet to be "fixed" someday.
