Keep in mind that you are most likely buying this machine for a machine that is not designed for hat embroidery, so Brothers and Baby Locks do not make hat embroidery frames. With that in mind, yes, you may find it difficult to use. The hardest part is laying it flat on a car that isn't made for headgear. It's not about whether it fits my car, it's about attaching it to an existing tire and that tire will fit your car. This works fine for a pair of hats, but you won't be making production runsβ¦
