Wow! It pays to cruise other stitching blogs. I saw a Celtic-style wip on a blog, and I searched the designer, and found this website: http://www.inkcircles.com/index.html.
Beautiful charts, all Celtic inspired! They have a "goodies" section which has 2 years worth of monthly freebies. For 2008 they've been doing a mystery SAL. The good thing about coming part way in something like this is you get to see more pieces of the puzzle! I may have found a new WIP for after Christmas, if I can wait that long!
