You're welcome. The trick to finding it was by googling Patons "Moss Stitch Set" 6 months. The key was putting the quotes around "Moss Stitch Set" so that it would look for those specific words in that specific order.
It actually came up several times, in several places to purchase it, so they must have printed a lot of copies--I'm betting you'll be able to find it.
Glad I could help.
