I find I am using books like these ones more and more for general inspiration and less and less for the actual patterns they contain. For me it's all about the eye candy .... not just the quilts themselves but also the settings in which they are photographed. Beautiful textiles in gorgeous photographs make me feel good! They give me inspiration to sit down at the sewing machine and start playing with fabrics.
But I find that the actual patterns are so (often) self-evident or rehashed from previous books, that I tend not to actually use them. I guess there's not a lot new about patchworking. There's only so many ways one can sew squares, rectangles and triangles.
In addition to these sorts of books, I have begun looking to general design and pattern books for inspiration. Books about interiors. Books about architectural style. Books full of lovely photographs to inspire the imagination.
Where do you look for your creative inspiration?
