Yarn or crochet thread of any kind, any color. Surprise me! Challenge me! (I'll find a pattern to make.) My favorite colors are khakis, greenish-greys, mossy greens, etc. Or tomato reds. But I can always make something in a non-favorite color as a present for someone else. (But, you gotta know: socks aren't likely to happen soon.)
Books! My Amazon Wish List is up-to-date. My sister and family shop from the list for my birthday and for Christmas, and my sister probably already has raided the list to shop for the whole family's gifts to me. (My birthday is at the end of November). If you get me something from there, please mark it as purchased. I promise not to peek at the list.
Oh, and chocolate is always good. ;)
