As I was beginning to ponder what it would take to create knitted bark that was outside wrapped around a tree in New England for five months, I thought that some testing would be in order. I am thinking that I need to use acrylic yarn so that it doesn’t disintegrate while exposed to the elements, but I hate acrylic. I really want to use natural fiber. So I created test swatches of acrylic and acrylic blend yarn as well as wool to see how they hold up. They are stapled to my fence and I will test them over the next little while to see how they do. It's exciting to have a little time to experiment and find just the right fiber.
