Annaquilts,
That was a joke, the truth is I'm the one on the leash
My wife's youngest son was allergic to about everything when he was a kid. Including cats. My wife fixed that problem by bathing the cats to keep the dander down, and making him home made stuffed toys out of hypoallergenic washable materials.
He still has the first teddy bear she ever made him.
irishrose,
I'm thinking some tension problems are caused by gremlins. Machines that sew along perfectly then suddenly the tension goes wonky. Our 4622A has just done that. I've done everything but remove the top tension and take it apart to clean the assembly.
It went from sewing beautifully with the adjusting knob on '3' to be too tight. I finally got it to sew again but now the knob is on '2'. Probably some lint in there somewhere.
