Nap: Certain fabrics, such as velvet, velveteen, and corduroy, have fuzz or pile which called the nap. Nap usually runs in one direction. Run your hand across the fabric and the nap may be dull when smoothed in one direction and shiny when smoothed in the opposite direction. Because of this tendency, it is important to cut all pieces of your pattern with the nap; a with the nap lay out is shown on the instruction sheet. For a different look, pieces with the nap going in opposite directions may be used.
Narrow hem: A narrow hem measures ¼ to ⅛”. Narrow hems are used in a variety of garments, such as blouses, shirts, slips, and other lingerie. Narrow hems are also used on household items, such as tablecloths, placemats, and napkins.
Needle: Both hand sewing needles and machine needles come in a variety of sizes and types. The needle used depends are the fabric being sewn and the look you are trying to achieve.
Notch: Inward curves are notched, meaning small wedges are cut out of the seam allowances at certain points. A notch also refers to the markings on a commercial pattern designed to help you match the fabric pieces together correctly. These types of notches may be cut outward, as shown on the pattern; some people prefer to simply make a small snip in the fabric, rather than using notches.
Notion: A sewing notion is anything other than the sewing machine or the fabric, which is used for sewing. Thread, buttons, elastic, and lace are notions and so are the tools used in sewing, such as pins, pin cushions, gauges, thimbles, needles, scissors, and so on.
