Hello I am a machine knitter always looking for vintage manuals, patterns and magazines on knitting machines. Maybe these pdf books will help you in your learning process. I'll be adding more downloadable pdf books in the coming weeks so make sure to favorite my shop:) A great supply of patterns for both punch card and electronic knitting machines. Also some multi color jacquard patterns at the end of the book. Once you order my pdf you should receive a downloadable copy instantly. You can use Adobe Acrobat to view this pdf. Use this link to download it for free: https://get.adobe.com/reader/ When it comes to downloadable pdf orders I cannot offer refunds but if you have any issues with your order, please feel free to message me.
