Rosemary Makhan died in January of 2014, and her website where the patterns were sold was taken down at that time. I see that her blogspot is still up, but no patterns are sold there:

Your best bet is to contact her husband, as he may have some patterns of hers left. Last year someone in Australia was looking for a different set of patterns by her, and Rosemary's husband was able to help. Try Googling her name to find contact info.
Edit: There is also a Yahoo group for Woodland Creatures. The last post there was in 2014, but you could try joining and posting; maybe someone on that group has the pattern and is willing to sell it. You can also post on the SewItsForSale group as an ISO (In Search Of). To access, go to groups.yahoo.com and search for WoodlandCreatures and SewItsForSale.
