I'll have to take that apart, as I don't see a hole for the thread to go through. I'll keep you informed.
I took your advice and wound a bobbin with the same thread I'm using on top and things are definitely sewing better.
What material would you recommend to practice sewing in general? Canvas, vinyl...? Right now I'm using scrap felt from when I recovered my pool table. It is pretty heavy stuff. I was able to easily sew through 4 layers.
I spent my web surfing time reading all your Tutorials and other things you have posted. Great info and thanks for helping us DIY'ers.
Jack of all, Master of none. That's Hot Rodding!
