I had a comment posted to the website from a Daniela, but no return email address, so I will answer it here. She was asking about feltable roving for a fundraiser art project for her kids school.
My answer is the Merino Roving would probably work best for the project. Everything I have is available on the website here. It is feltable and would work well for needle felting as well as wet felting.
Hopefully that is the right answer. I really hope I can get the message back to her!
