Many people also like to use self-threading needles. For hand sewing, these needles are widely available, but self-threading machine needles are more difficult to find. Either means of threading needles is workable. Most sewing machines come equipped with a seam guide to be screwed onto the machine table to the right of the presser foot. These guides can generally be purchased separately if desired, and other types of guides are also available.
Some blind people like to put tape on their machines as guides.
Some people find they can guide the material by keeping one finger on the edge of the material and another finger on the presser foot. Regardless of the kind of sewing guide used, the procedure is the same. To make a good-looking garment, one must be a good ripper. To rip, one needs to feel the threads of the seam to be ripped and get the point of a standard ripper under the stitches. If the fabric is lightweight or knitted, this can be delicate work.
