I'm hoping someone can help me out - at least give me an idea of what the issue might be in this case. I'm new to sewing and machines so if this is a really obvious question, forgive me.
My machine doesn't feed the fabric through when I'm sewing - it just stays in one place and creates a knot! This just started happening today and I've done all the stuff that seemed obvious to me like removing the bobbin and checking to make sure there wasn't a thread jam, rethreading, etc. I've had the machine for about a month and it's been working fine up until today (got it used on craigslist- the previous owner had it for about six months and only used it a few times).
If anyone has a general idea, or if it seems like I just need to take it to a sewing shop to get it checked out, let me know!
