Wizcrafts Report post Posted January 29, 2022 Your needle is much too small for the thread you are using! For v138 thread on top and v92 in the bobbin, you should use a #22 needle. It should be a leather point, preferably an S or LR point. If you must have the tightest holes, try a #21 needle. Here is a needle and thread chart that may help you choose the best combinations.

You can see the knots on the bobbin side and it looks loose. I would also consider changing the Serafil thread as I have found it to be a very slippery thread and sometimes hard to get a even tension happening.
