Thanks all, sad to say I have tried all those things. I did change my needle to 11/75 due to someones suggestion.
I cleaned several times, changed needles, changed tension several times. tried different threads and now I am totally confused. It seems when I do straight sewing it cooperates, but when I want to change to fmq I cant seem to get it right.
If you will tell me when you fmq what is your tension, what size needle, what weight and type thread?
Every time there was a sale of essential thread, I bought several, I think I have every color.
