Are you talking about fabrics, colors or design? It's a touchy subject, one that I try to stay away from in my group. I personally only give quilts that I would like myself. If I don't want to give it then I'm content.
If the fabric is decent, and you have quality sewing so that it will stay together after many washings-ugly is in the eye of the beholder. Some colors and patterns don't really appeal to me but somebody else may like it.
