Honestly! I Know Better

I have just been sewing for 45-60. I have been chain sewing (not cutting each time you finish a piece.) I cut 2 of the chain sewn piece apart to sew them together and discovered that my bobbin tension is off. Not only on those 2 pieces, but EVERYTHING I've sewed in the last hour. I could scream. I really need a new machine. I've priced them out and know exactly what I want. However, I'm not buying it until I have the cash and that will be next Feb or March. In the meantime; I need to do what I've been telling myself and that is checking the pieces as I sew and not assuming everything is working out fine.
