C-Lon® Thread is a UV resistant monochord that is soft and flexible. Available in nine colors and two sizes, this cord is best used with seed beads. The size D that we offer is ideal for use with size 11/0 seed beads and the size AA is great for use with size 15/0 seed beads. Lightly coat the thread with beeswax before stringing to help protect against fray and water damage.

FireLine® interknitted thread for jewelry-making is designed for stringing and weaving projects and is recognized as the strongest fiber per diameter ever created. The advanced technology used to create FireLine provides an ultra-thin diameter that is three times stronger than regular monofilament. FireLine is also UV protected, so it won't deteriorate because of exposure to sunlight. This thread does not stretch or tangle, threads effortlessly and resists abrasion from beads that have sharp or rough edges. This material is great for use when weaving Swarovski crystal, seed beads and gemstone beads. We offer FireLine in nine diameters and six colors.

Griffin Natural Silk is perfect for stringing pearls and other beads. This material is available in thicker diameters than most silk thread, allowing you the option of working with larger bead holes. The drape and softness of this thread allows for stringing, knotting and braiding techniques to be used. This silk thread is available in 20 colors and 13 diameters that range from 0.3 to 1.05 millimeters.

Griffin Nylon Power is a glossy extra-strong thread that can be used in almost any type of technique. Special stretch-tension material allows the thread to expand when pulled and then return to the original size--allowing for precision knotting. The 20 designer colors are offered in 13 diameters that range from 0.3 to 1.05mm.

Kevlar is incredibly strong thread that is used to make bulletproof vests. This material is easy to cut, yet almost impossible to break. Kevlar thread can be used in stringing and weaving designs. Use fisherman-type knots when tying Kevlar, as overhand knots will weaken the thread. Kevlar is available on 50-yard spools in two colors, natural yellow and dyed black.

Nymo® is a nylon thread the size of dental floss that is specifically made for working with seed beads. We recommend coating your thread with beeswax or Thread Heaven® before beginning any seed or bugle bead project; keeping the thread from fraying and adding durability.

Purely Silk™ Thread is used when beading soft gem materials, such as pearls and amber. This is often chosen for decorative use alone and with beads. Purely Silk Thread is soft and sleek and comes in a rainbow of colors. Use the colors to enhance your beads.

Purely Silk Thread is available in bulk spools, cards and on cards with a needle already attached.

Silamide Beading Thread is a twisted 2-ply waxed nylon thread with flexibility, strength, resilience and colorfastness. This thread is ideal for peyote stitch, brick stitch, loom weaving, and stringing beads with small holes. We offer size A (0.203mm) in 24 shades on 40 yard cards.

Silkon® Nylon-Bonded Thread is used for harder beads that tend to have abrasive-edged holes that can damage silk; such as garnet, crystal, amethyst and metal beads. This thread comes in a wide variety of colors and knots very well. Just like with silk thread, use the available shades to enhance the colors of your beads. Silkon is sold in 20-yard and 100-yard spools without a needle.

It has a tensile strength 10 times stronger than steel, with superior abrasion resistance.

Aluminum Wire is soft enough to manipulate without the use of tools. This wire is available in a rainbow of colors, which are applied five times during the manufacturing process. This tarnish-resistant wire can be used for wire-wrapping, but is too soft to support weight. We offer this wire in seven different gauges to accommodate all types of jewelry and craft projects.

Beading Wire such as Accu-Flex® and Acculon™, is a twisted stainless steel wire with a plastic coating that is used to string beads. This type of construction provides flexibility for nice drape along with durability against the rough edges of bead holes. The diameters and thread count (more threads mean more flexibility) of beading wire range greatly to accommodate all types of preferences. There are also quite a few colors and even glow-in-the dark effects to choose from. No beading needle is required with this type of stringing material.

Memory Wire is rigid and pre-coiled wire that makes simple and stylish rings, bracelets and necklaces. You can create a single- or multi-strand look, simply by deciding where to cut the wire with your memory wire shears. We offer memory wire in stainless steel and basic carbon steel; both gold and silver tones are available in a range of diameters.

Niobium is a metal first engineered to protect hypersonic aerospace vehicles from extreme conditions. The natural grey color is considered hypoallergenic. Although the nine anodized jewel-tone colors are not certified as hypoallergenic, most metal sensitive people can wear them comfortably.

Precious Metal Wire is used for wire-wrapping, chain making and other jewelry construction. Precious metal wire is available in four metals (gold-filled, sterling silver, Argentium® sterling silver and sterling silver-filled) and in three tempers (dead-soft, half-hard and full-hard). Most of these wires are available in round, half-round, square, twisted round and twisted square shapes.
Dead-Soft Wire is extremely malleable and can be bent easily into a myriad of shapes. It does not hold its shape in stress situations, such as clasps.

Half-Hard Wire is a malleable; however, it will maintain an intricate shape under moderate stress. This temper is useful for weight-bearing parts of wire-wrapped jewelry.

Full-Hard Wire is harder to shape, but holds intricate designs well. This type of wire is excellent to use when creating clasps.

Super-Thin Beading Wire is 34-gauge wire that is used in wrapping, stitching and wire crochet projects. This wire comes in gold and silver color. Each spool contains 24 yards. Because the wire is so fine, it will accommodate almost any drill hole. This should be used with lightweight beads only, as it doesn't have much tensile strength.

Wrapit® Wire is for all types of wirework and is easy to shape. This wire is considered dead-soft, the most pliable type of jeweler's wire. The wire has an anti-tarnish coating for a long-lasting shine and is packaged on handy reusable plastic spools.
