Stretch velvet or woven? If it's stretch its going to be a booger! You have to be very careful in pressing velvet of any kind---use a pressing cloth and only from the back. It looks beautiful in quilts and used to be used a lot in crazy guilts. However, it can be used in almost any type of pattern. I'd keep it very simple though and use appropriate fabrics such as silks, satins, and light weight borcades with it.
