Put the big hammers down and walk away from the machine.
At one point we have all wanted to toss our machines and a few quilts out the proverbial window. Go find an adult bevy, if that's in your lifestyle and chill. Someone will be able to talk you through it tomorrow. I have to admit I haven't read your previous post, but I do understand the frustration. Been there, don't like it. Hugs, and just know there is a solution out there, We have some great gals, here in BC that can talk you through some of your issues, Give the list a chance. And there is a wealth of knowledge on our list, even though some of them aren't as close geographically. Shut the damn machine off, shut the door and go outside and yell outloud. Oh wait, you're in White Rock, up here, I can go outside and yell, and no one calls the cops.
Do you have any machine maintenance DVD's. They are sometimes a wealth of information. I wish you luck, and keep talking to the list, we are listening. Marion in BC
