Though I didn't use it for piecing I did make quite a bit of clothing with it including a wedding dress. It was an Elna SU62. It traveled to a number of states with me, got it back in 1978 and it never saw the inside of a repair shop. Heck back then I didn't know you were supposed to take them in to have cleaned, etc. Can't remember if I ever put a drop of oil in it either. Anyway, I sold it once I got my Viking Designer 1 in 2000 thinking I didn't need 2 machines. Boy was I wrong. Tried to buy it back from the lady I sold it to for twice the money and no deal. She fell in love with it too. My loss.
Anyway, it was a great machine, light enough to carry to class, the case made into a table that slid into the arm of the machine so you had a free arm and table model all in one.
Now my Viking D1 is my piecing machine and I love that one too. Though its an embroidery machine since acquiring another embroidery machine I use the D1 strictly for piecing. I love the way that I can program special stitches such as the scant 1/4" and save it so I don't have to reprogram it every time I turn the machine on. Plus it has semi-auto needle threader, auto thread cutter and the auto foot raiser or whatever its called with needle down makes strip piecing a breeze. Yes, I love my D1 and hope it lasts forever.
