Help....I just used a mono-poly in both top and bottom threads in a quilt(comfort quilt for a child with CF) that is to be used. Is this not a good thing?? Per a suggestion from a tutorial. (to use the same thread in the top and bottom)
I bought the thread it at a LQS. "As it hides a multitude of sins" I used it for SID only. I am confused...

I did have problems with breakage until I changed to a smaller needle (75/11).
