Thanks for all the info on the 306. I purchased a black,one last summer and finally got around to ordering the bobbins and needles from the internet. It only came with 2 bobbins and the one needle. Couldn't find needles other than size 12 and 14 so I'm guessing that's the only size they made for this machine. Now I need to get it out and sew in it - along with all my other "babies". I'm going up to the Lancaster, PA show and I just might find something new from the vendor I've purchased from many times before. He's over at the Comtinental Hotel show - Pennsylvania Quilter is the vendor's name.
