I know mine have. When I started out cross stitching some 35 years ago (yes, it's been that long), I had very simple tastes. I think the first cross stitch I finished was a Precious Moments. After I stitched that first one, I bought all the Precious Moments charts I could find. Now I'm not even sure where most of them are any more. Then as I got a little bit more skilled (okay, a lot more skilled), I started stitching samplers and discovered Just Nan. I bought every pattern she came out with. About 5 years ago, I discovered I hadn't stitched any of her designs in several years. I wasn't buying to stitch, I was buying to collect. And honestly her designs have become a LOT more expensive then they were. I love the old style Shepherd's Bush. Here's their Noah's Ark that I did about 10 years ago.Then they changed their style of writing and I really haven't found any of their new designs I would spend money on. Thank goodness I still have a bunch of their older kits still to be stitched.
There are a few designers that I have loved from their beginning and still love them. Lizzie Kate and Prairie Schooler are two that come to mind. I love Lizzie Kate's use of color and I really like Prairie Schooler's modern primitive look. I'm still drawn to their designs after all these years.
So while my tastes in designs have changed, one thing hasn't after all these years (really, 35?!). And that is my love of the art of cross stitch.
