Let me start by saying, IMO, the Elna is not for quilting. I like a straight stitch machine for piecing - the Elna liked to eat points on HSTs but the big problem is self adjusting presser foot. You cannot manually adjust it and sometimes you need less pressure, especially if you try to do any quilting. I did SITD one quilt on it before I bought the 301, but it wasn't fun.
Now with that said, I have to tell you that that little machine has sewn anything that could be forced under the presser foot - fire retardant racing suits, men's suits, wedding dresses, bathing suits, drapes, upholstery with heavy velour fabric, 2 layers of men's belt leather, tennis shoes, almost every dress or pair of dress pants my family wore. It has a very pretty satin stitch and can fake a buttonhole stitch for applique. And it never complains. The paint on the bed is chipped - I've noticed that on some other of the light blue ones, too. If she has to have a flaw, I'd rather have it in the paint that the stitch. Speaking of which because it a Swiss made machine with tight tolerances, the stitch is prefect. My daughters used to tell each other to be careful not to make a mistake with Mom's machine because it's too hard to pick out.
I did make three quilt tops with it years ago, but I went upstairs to my old Kenmore to do the quilting.
