your hats are very cute- but i have a question....if you can sit & crochet, why can you not sit & sew? there are lots of hand piecing projects that are fun, easy and would fill that (void)...english paper piecing or cathedral windows are both projects that are easy to do...
just wondering- what the difference is in your (limitations) that is keeping you from being able to quilt/sew?
great hat's though- & a great reason for making them
