The machine adopts the left side not on the yarn. I mean, at no matter what stitch pattern, it is only the right part "stitched". Links the machine stabs though, but the thread does not pass through the fabric and intertwined with each other. Not even the left-side straight-stitch work.
I have now at least 100 times threaded exactly as directed with different brand yarns, all kinds of brand needles used in different strengths, set everything can somehow adjust the bobbin newly wound (sometimes with another machine). Say, I have thus spent hours and hours trying to sew with this machine a little ... but it just does not work !!
Sew letters or numbers is of course not to think - especially disappointing, because this function was the main reason for me to purchase this machine
CONCLUSION: absolutely not recommended!
