I have two scouts in the family and I don't sew. I thought that buying this inexpensive "sewing center" would save me a few dollars or finger pricks by letting me easily sew on my children's patches.I was dead wrong. I think the model I got is missing a piece because the thread bunches up from the bobbin underneath and the machine freezes up after less than an inch of sewing. I have followed directions in threading the machine, but when I look at the photo of the bobbin case there seems to be a bit of metal that my machine does not have.I am so disappointed and am just going to have to throw this little time waster away. I could have sewed on several patches by hand in the amount of time I have spent trying to get it to work today.
