HELP with sewing machine messing up!
I was sewing right along and noticed my top (upper) stitch was fine but the lower had almost a loopy design to it almost like a rounded zig-zag pattern. I did not touch any of the tensions. The only thing was re-loading the bobbin. I noticed that the thread may jump out of the tension adjusting spring. I have a Brother XL 3500 i. This is what I hate about sewing!!!
Any suggestions? Thanks!
