I have had a Juki LU-562 for over 10 years that never skips stitches when top stitching vinyl material. However, I started sewing a thicker version of vinyl like what would be used to reupholster a John Deere tractor seat. The supplier who sold the vinyl to me said that another upholstery shop said the material was impossible to top stitch without skipping stitches. So, what would you tell me to adjust on my machine other than replacing the needle? I like the material and would like to finish using it as I bought three rolls due to the price. Basically, I have no formal training on my machine or how to adjust it. I have tried to review all the Youtube videos on the Juki LU-562/563. Thanks in advance!!!
