There are very few hard-fast rules when it comes to selecting the embroidery thread. Use the type of thread or weight that looks best or has the effect you want to achieve in your project. Experimentation is often the best indicator of whether or not a thread will give you the desired look. Always use threads from the same manufacturer in an embroidery project that uses floss, as the finish on the threads can vary from shiny to matte. Pearl cotton is available in a variety of weights or thicknesses, and depending on the weight can be available in a twisted skein or a ball. A wide range of colors is available for size 5 pearl cotton, with a lesser variety for size 8. Other sizes have a limited color selection. When selecting pearl cotton, remember that the larger the number, the finer the thread. Silk threads for embroidery are available in embroidery floss, pearl, and other weights, as well as fine ribbon. Use silk thread as you would any other thread. Narrow weights of metallic thread can be stitched directly onto the fabric, while thicker or wired varieties should be couched to the surface of the project. Weights for metallic threads can be very fine and whispy to very thick and somewhat stiff. Metallics are also available in floss, single-ply, or pearl cotton varieties. Colors include gold, silver, and platinum as well as copper and antique or aged versions. Synthetics can be unruly to stitch with, so keep some thread conditioner handy when using these types of threads. Overdyed threads are not to be confused with variegated thread or floss, which features varying shades of a single color. This thread is used in ribbon embroidery, utilizing a variety of surface embroidery stitches, or it can be used as a decorative accent with other types of embroidery. Use a laying tool when stitching using multiple strands of floche to keep the stitches smooth and even. These types of threads can be difficult to work with, so be sure to choose an appropriate, often simple embroidery stitch. Otherwise, you could be fighting a losing battle with the thread. These threads can be bent, twisted, and curled and hold their shape due to the hidden interior wire. The most common wired threads are Kreinik’s HotWire and DMC’s Color Infusions Memory Thread.
