You are so lucky to have found a 628 Singer machine! I love it for the bobbin filling in place. I have other machines and if I run out of bobbin thread, I have to stop and fill them outside the machine. To help this problem, I fill several bobbins only to have some left over at the end of the job. I truly love this machine. It is faster than newer ones too. I have a Viking machine and it is twice as fast as the Viking. I hope you enjoy your 628.
