Review on Simthread 25pcs 90WT Prewound Bobbin Thread Set: Size A Class 15 (SA156) with Storage Case - White, 60S/2 - Perfect for Brother Embroidery and Sewing Machines! by Satsuki Silva

I have a Singer stylist and couldn't thread the bobbins properly. My fault for the optical problem. These bobbins fit perfectly and are perfectly threaded. Therefore, with the correct winding method and correct tension, I have no skipped stitches or problems with the machine. weight matters. 90 gauge is good for my regular sewing. In my project this is sewing patchwork blocks. That's why I work with fabrics made of 100% cotton. My rating is based on that. I had another set but later realized I didn't need this. I'm very satisfied.
