Sorry for the delay in my reply - you can use any fabric content but it's easiest to hook with soft, flexible fabrics like t shirt, chiffon, soft sweaters, yarns. Harder fabrics like quilting fabric, denim, hard ribbons are more challenging to hook with.
Probably since it cuts through felted wool, but I have not tried so I can't say for sure! Maybe try reaching out to Old Tattered Flag since they manufacture the blades and would probably know. Thanks!
