This wool is made by monks at Mount Saviour Monastery, located outside Elmira, NY. To my knowledge it is only available at the Monastery or online here: https://msaviour.org/wool_skeins.php.
There are currently 9 colors offered on the web page, but it’s best to call or email the monastery to find out what’s actually available (including some colors not included on the web page -- check the stash tab for this yarn to see some other colors that have been and might again be available).
