I can give you a file for all type of machines(Needles) separate. Your manufacturer (production) does not need to do any additional work. I can do it perfect. If you want to see my work, check out Funatic or FootCardigan. I worked for many other clients, but these are just some of very important for me.
Each sock/design need file for production, so I can guarantee you an excellent work. Work ONLY with me and you do not need anything others. Your problem is solved and your future product is done very quickly. I will save your time and I will deliver all in few hour.
