Question about sewing thick fabrics
I hope someone can help me with this. I have a basic Kenmore sewing machine that has always been a very good machine. Now I am sewing microwave cozys and my machine is not sewing smoothly through the batting and fabric thickness, especially when sewing the two sides together. It sounds like a shopping cart with a bad wheel! I have changed needles, I tried a #11 and a 14 and cleaned the bobbin area and it's still noisy. The tension is fine. The stitches look nice and flat. It sews fine and quietly when piecing two layers of cotton. Any suggestions would be appreciated.
Thanks
