And don't try to use the good fabric scissors as a thread sniper... The thread does get cut, but you might just end up lying on the sofa with your finger stuck in the air for the next couple of hours, to try to stem the blood flow from that huge gap in your fingertip... And you certainly won't be oing any sewing during the next few days!
When winding the bobbin, try to keep your attention on the bobbin, and not end up with a quarter spool being wound all over your bobbin and half the sewing machine. If sewing a seam is suddenly much harder going, STOP and investigate, I've sewn parts of the backing, the other side of the quilt, my clothing and whatever else was in the area into my quilts. And if you get tired, have a break! I generally do all the stupid things when I want to 'do just that one other seam - it won't take a minute'. But fixing it will probably take an hour or longer!!!
