Review on Janome Plastic Bobbins: Essential Accessories for All Home Sewing Machines by Amber Perez

They are not as strong or heavy as the bobbins that came with my Janome, but they work very well and I didn't have to adjust the bobbin tension. on my current Janome 2212 machine. I'm a beginner and have only been sewing for 4 or 5 years. Unless you're an experienced manufacturer, it's worth choosing a brand name, rather than a generic brand substitute, whenever possible/available in order to buy right the first time (unlike ME, who constantly falls into the trap of only ending up to be a little cheaper spend more on replacement.ugh)
