In response to a discussion on sewing fine fabrics without puckering, I decided to once again highlight my Singer 401. (Previously, I did a post about stitching stretch fabrics on this machine.) Machines are most often demonstrated sewing through multiple layers of denim or leather - even aluminum cans - to prove how strong they are. But it is just as important that you can sew delicate fabrics.
Naturally, I'm partial to vintage Singer machines, so I'm going to demonstrate how well some of them really sew. They can hold their own and even excel against modern machines. If you consider the price point (I bought this one for $50 including the cabinet) you can't beat it at ten times that amount. Few machines made today - and certainly not in an affordable category - can sew better than this.
So for the lightweight fabric I'm using this. Its a very light, sheer cotton/polyester blend.
It's important to use the right needle and thread, of course. Fine thread and size 9 needle.
For best results, use the straight stitch foot with the straight stitch throat plate. This prevents very fine fabrics from being pushed down into the feed dogs by the needle and having your fabric chewed up.
And set your machine with the lightest presser foot pressure adjustment (that knob on top left screwed almost all the way out), a very short stitch (about 20 stitches/inch), and a light upper tension. The 401, as well as most Singers of this era, has all these adjustments so you can really fine-tune your sewing. Nothing is automatic here, you make all these adjustments with knobs and levers.
