sewing and embroidery machine needles are available in many types – sharps, wedge (cutting) points, ball points & metallics.
a sharp point is good for most woven fabrics that won’t unravel. sharps cut through the fibers, and deliver the thread with less push and pull on the fabric.
ball points are used with knits and other stretchy fabrics when it’s important to avoid cutting the goods by needle penetration. the rounded points will cause the needle to slip between the fabric threads to prevent cutting the fabric and causing it to unravel.
wedge points are for leather, vinyl and other heavy and very dense materials. these needles are for fabrics which are not woven as they make a small slit rather than hole. the wrong needle on leather would cut the design out.
fortunately, needle manufacturers have also designed marvelous needles for specialty embroidery thread like metallic, glitter and other delicate exotic fibers. specialty needles (like sullivan’s metafil, madeira’s metallic, schmetz metallica etc..) have larger coated eyes and deeper scarfs to handle the thread more easily.
don’t forget to test-stitch the design with the type of needle you’re going to use on final project. there are always exceptions to the rules, and it’s always a good idea test the needle and other components before using them on final projecs to avoid unpleasant surprises.

Pin Tips

Ball heads are made of either plastic or glass. While plastic heads are less expensive than glass heads, they will melt from the heat of an iron, so go for glass heads if your budget allows. Ball heads (either plastic or glass) are one step up from the flat head, and I prefer these pins for all of my sewing because not only are they easier to see, but the head is easier to grab hold of for inserting and pulling out of the fabric. Ball head pins are great for use on heavier or bulkier fabrics such as denim or fleece.
Brass pins are usually nickel-plated, have very sharp points, and typically will not rust. I’m not too hot for brass pins because the nickel-plating sometimes leaves black marks on fabric that are not easy to remove, but if you’re working with dark fabric, this doesn’t pose much of a problem. These 1-1/16″ nickel-plated brass silk pins have a finer shaft which allows them to glide through delicate fabrics without damaging. The sturdy brass construction makes them strong enough to use on thicker fabrics, too. Again, watch out for any untoward markings on your fabrics which may be left behind the nickel-plating.
Steel pins are the least expensive, but the steel may rust. With a bit of hunting, you can find steel pins that are nickel-plated, which helps prevent rusting. Steel pins are stronger than brass, which is great for working with heavy wools or drapery fabric. A magnetic pin holder comes in handy for gathering up loose steel pins quickly, but remember not to put it near an embroidery machine or other electronic device because it may damage computer chips.
