Stitch count is 198 x 262.
The Tanglewood Celtic pattern was originally published in the September/October 2007 issue of Just CrossStitch Magazine, which is available through the company website as a back-issue. If you're stitching from the magazine, please download this correction page. Stitcher's have helped locate a few spots on the chart where the magazine was off.
The good news for those who can't get the magazine: the chart is now available here as a stand-alone leaflet (with all the corrections made.)
This chart is also available in PDF format.
