Both. Depends on what look I want to give the quilt, whether I want to take it travelling with me, or to do whilst waiting in the doctor's office. Most people like the over - all effect of the quilt, rather than the fact that it is hand done. Therefore, it is faster and cheaper to produce a similar result.
I also think it is up-to-date to use a machine. After all, most of us don't go out and milk a cow when we want some milk any more do we?
