Machine work that can accomplish this type of thread pattern.
Hello all! My girlfriend and myself have been creating custom sweatshirts for people by hand. We are way in over our heads with orders and need machine assistance if we want this business to take off. The stitch pattern we are doing is a stem stitch with embroidery floss, usually onto a cotton sweatshirt. What we are looking for is a machine (preferably automated) that has the capability of creating this type of pattern with a thicker thread. Any and all advice is welcome. See the attachments for the example. Thanks!
You might want to look at either a sashiko or embroidery machine. Good luck!
