I sometimes use wof good when ive used 108 wide fabric as less joins, for binding, sometimes I use the length particularly if its a strip I've saved from trimming the extra off of a backing of another quilt and it matches and I've also used bias because I like the way the bias cut looks. it's my quilt and I cut my binding depending on what I fancy and what fabric I have at the time. The quilt police dont visit my house
