THANK YOU everyone I will pass the info on to my nephew - I doubt he will ever use them but he was curious- and I said I know just the place to get the info
He may play with them on the machine - just to see how they work
He has the machine in his room but tells his friends it is his moms she is just "storing" it in his room - at 13 and a guy it just isn't cool to sew LOL
