I knew sewing machines sew forward and reverse, but, super speed?
I told my sister, I would make her a quilt, but, I was currently working on one, and it would be awhile before I started one for her. She said how long? I said I can't put a time on it. I have alot to do to make a quilt. How long you going to take?? I can't say, the way I work could be about 3-5 months. 3-5 months!!! Is that what you said??
I would try to be brief but, friendly telling her you don't work by clocks, and are not sure you could meet her time frame and suggest someone else
