Twin Hole Beads or Superduos
Twin hole beads and Superduos are some of the emerging shaped seed beads. Like the Tile beads, they are different because each bead has two holes instead of just one, presenting new challenges for design.
You may be wondering about the different names. Although these two beads look remarkably similar, they are actually made by different manufacturers. Twin Hole beads were launched by Preciosa. Superduos are made by companies that include Czechmates and Matubo.
Both beads measure about 2.5mm x 5mm and their oval shape helps to create very interesting patterns and texture. Aside from working out how to join these beads in ways that hide the thread – if you just move from one hole to the next in the same bead, the thread is visible up the side of the bead – they can be challenging to use. As with all beads, it is not uncommon to find that the hole has been blocked, sometimes with a small chip of glass that got lodged during the manufacturing process. With single-holed beads, you realise straightaway if a blocked hole renders a bead useless. With twin hole beads it is possible, indeed common, to find that one hole is perfectly fine, while the second hole is blocked or damaged. If you happen to thread through the ‘good’ hole
when you pick up the bead, you may not discover the problem with the second hole until you have added a whole row of bead-weaving and come back to the bead to pass through its second hole. At this point, you have two options: try to ease the blockage out of the hole, or undo your work back to the point where you first picked up the bead, and replace it. By all means try to remove the blockage, but be warned, it often results in the fragile glass around the hole splitting and a completely broken bead, in which case, undo your work and replace the problematic bead. As a tip, when you pick up a twin hole bead, test both holes, either visually or with your needle, before using it – it saves a lot of frustration later on!
‘Superduos’ and ‘Twin Holes’ are similar, but the manufacturers use very different finishing processes, so the appearance of the beads differs in terms of the quality and depth of colour. If you look very closely, you will see that the Superduos have a slightly more pointed central section (between the two holes) than the Twin Holes, but this is barely noticeable. If a pattern advises a particular brand of bead, then I recommend sticking to that as there could be a good reason why the designer made that choice. If you find this idea confusing, then think of it as being like the seed bead brands – minuscule differences in size and shape can add up to a big difference in the way the beads sit in your finished project. However, as with everything, there is nothing wrong with a little experimentation, so if you are playing with these beads, try both brands and see what you feel is different about them.
If you want something to get you started, there’s a beginner’s herringbone twin hole bead pattern here. You can also try working in Peyote stitch with this beginner’s bracelet. My Very Hungry Caterpillar Bracelet also uses simple a Superduo stitch to create the bracelet. Or, you may also enjoy the simple thread path to create this Twin Hole waves bracelet.
