Yikes..just the thought makes me want to cry for you.......hate when we do things in haste or just forget absent mindly....but we are not perfect and we learn from our crazy mistakes...so step back and hope that your machine gets fixed quickly so you can return to your sewing.....I have a question couldnt they lend you a machine until yours was being fixed?.......I have two machines and trust me when one gets ill the other does the work so you may want to think about buying a less expensive machine for times like this.....god bless.....Trish
P.S.........dont use pins while your on your sewing machine.....I use fabric glue its not permanent but who cares its safer.
