Ugh!!!! :cry: I have spent most of the day trying to get the tension correct on my Avante - Wondering if it might be the cotton/bamboo fabric that I used for backing. Anyway, I have a towa gauge and my bobbin tension is about 200-240 - then I set the top and the bobbin thread show up on top - when I change it - then the top thread shows through the bottom. I am using Signature 100% cotton thread and the same in the bobbin - I believe its 30 or 50 wt. Wondering also if I need to change my needle - have cleaned the bobbin and oiled it - rethreaded etc. I will try again tomorrow.
