Gather Textiles is located in Edmonton Alberta, primarily an on-line yarn shop.

Spanning 10 years of lessons, this is a very comprehensive curriculum for multi-shaft weavers. It appears to be the industry standard for learning multi-shaft weaving on line

This is Kelly's membership site with much more in-depth content. I found this best for rigid heddle looms in particular but she covers most loom types including multi-shaft (floor and table) and inkle.

Kelly covers a wide variety of looms and techniques as well as personal thoughts on a wide range of topics. She is especially helpful if you are new to weaving and trying to decide what you enjoy as she has such a broad range of topics.
