I always try to encourage customers to collect feedback from their customers about their work. Not only does it ensure that it continues to be of a high quality the word of others about their craft goes a long way to instilling confidence with new customers who have not bought from or worked with them before.
Over the years I have received many lovely testimonials about my work. I have included here just a handful of the comments I have received about my more recent work in supporting art & craft marketing and website design. I have also included testimonials from my earlier work developing Book-It Software. Although this isn't my primary focus anymore, the lovely comments over many years doing that should give you a good idea of my professionalism in anything I undertake.
