Beaders have access to more threads and cords than ever before. The majority of them fall into one of two camps – nylon and gel-spun polyethylene (GSP, Dyneema, and Spectra Fiber are some names this product is marketed under). Some other products, notably aramid and polyester, are available as well.
No thread is perfect for all beading projects. Each product has its strengths and weaknesses, and some are better than others for certain applications. This guide describes the general characteristics of many of the available products. Note the different methods used to describe the size, weight, or strength of these threads. The PDF also includes a chart that shows the approximate equivalents in diameter between the various products. Click here to download the guide.
