I’ve been blessed with the lack of tension issues in my quilting career so far. I am quilting with a walking foot on my singer heavy duty. First my back thread was showing the top thread and was basically a straight line of thread. I always forget which direction to go with my tension number. A quick google search told me to turn the number down. I went from 4 to just above 2 and that fixed the straight back thread issue. Now my back thread feels very tight. So tight that if I pull the quilt, the back thread snaps.
Is this a bad thread issue (this is fairly new Guterman quilting cotton thread from Michael’s)? Or a tension issue (feels weird to keep going lower than 2)?
I’m also going to change my bobbin, needle, and rethread in case it’s one of those “simple” fixes. Any help or advice would be appreciated!
