I will be the first to admit that I don't take care of my body like a should. I haven't been stretching or doing yoga as regularly as I used to before and after spinning and knitting. The result is a sore shoulder and neck. I am now back to yoga and stretching, reading Carson Demers wonderful book Knitting Comfortably, and resting my shoulder.
Since I just can't just sit, I hunted for a fiber craft that uses different motions and muscles than spinning and knitting, and hit on embroidery. I used to stitch quite a bit and have all of the supplies (and then some).
I had several patterns and samplers on hand from Dropcloth (the patterns on the bottom, to the left and the one in progress) but felt the need to freshen my pattern stash. I bought three patterns from Cozy Blue (top right) and a nautical knitting themed kit from Hook, Line, and Tinker (top). I don't need any more patterns to stitch, but let me know if there is someone whose work you really like.
