When I was at Estes Park, I purchased a glindle from Bristlecone Artisan Heirlooms.
I was on their Ravelry group and I asked to be placed on the any glindle list. This is where you will get a message stating there is a glindle for sale if you would like to purchase it. It seems these are so popular now, you can only buy them at shows. The website is sold out in seconds once an update is made.
I received a message for a padauk glindle with a flower at the tip. I thought it a sign since it is the same wood I have for my spinner so I purchased it.
It came in the mail very quickly and I love the spin action.
