Yes and now I say at the beginning I prefer which patterns and fabric to use. I made just a table runner for a dear friend, an artist, who wanted something in dark greens and charcoal and light greys. He chose the fabric and the colours were gorgeous and the pattern an 8 point star, also gorgeous and a joy to watch evolving. But the hand quilting was murder on the eyes. Colours you don't like or can't work with are a difficulty and quilting, unless you do it professionally and don't care about these aspects of it is such a 'soul' and spiritual, meditative practice you should do something that brings you pleasure. It should be possible to find colours and patterns that are mutually satisfying. Maybe you can combine what he wants with some blocks in complementary tones or colours that are better for you, he'll probably like it better in the long run too.
