First on the table is the sewing machine needle. For this kind of bra, we are using stretch fabrics. It is mandatory to use a special type of needle. You can use a stretch needle or a ballpoint.
Sewing machines have a standard set of presser feet. Mine has these two. The first is my standard foot. Yours may be a bit different. We’ll be using it a lot and it is mandatory.
The second is a special foot. In my machine’s manual, it is used for invisible hemstitch. However, I found it very useful for a lot of other jobs. It has a small piece right in the middle that is a perfect guide when stitching.
Here is the rule: to sew bras using stretch fabric it is mandatory to have straight stitch and one-step zig-zag. If you do NOT have one-step zig-zag, you can’t sew this kind of bra. Straight stitch simply is not enough.Quote title
