The Rising Mill closed in June and all of the employees were terminated. Hence, the traditional supply of Stonehenge paper no longer exists. Here's the press release issued by the Neenah Paper Company, the outfit that bought the Rising Mill at the end of last year:

However, Legion Paper, a wholesale paper distributor, has announced they they have purchased the specification for Stonehenge paper and the rights to produce it, and will be offering a substitute that they will have made in another mill.

FWIW, Pearl Paint had some in their Canal Street store in New York in May, and I saw some in an art store in Bennington, VT a couple of weeks ago. So it's still possible to purchase it from dealers who had a significant stock. But for now the supply is definitely limited.
