The most common type of cross stitch thread that is used today is cross stitch floss. It consists of about 6 strands of thread that are twisted together. The strands are twisted together in a loose manner and therefore can be separated easily in case you need to use thinner thread for the cross stitch. While aida cloth with lower number of squares per inch may need all the six strands, the ones that are have smaller holes may require you to use only three or two strands of the floss. Cotton floss is made from mercerized cotton. The other kind of thread used in cross stitch is called DMC embroidery. These are essentially made from rayon, satin floss, linen floss or metallic floss. Some other kinds of thread used include Danish flower thread, silk and pearl cotton. Sometimes even wool thread or metallic thread is used.

Over the years the patterns and pictures that are available for cross stitch have become more intricate than ever. This has necessitated the need for colors and shades of cross stitch floss of various colors. There are a large number of shades that you can find of the same color in the various cross stitch threads that are available.

Cross stitch thread is dyed to create the specific colors and hues that are required. There are also some kind of cross stitch flosses that are hand dyed. This results in a varying pattern of color on the thread and is used in some kinds of designs.
