Most designs supposed to be done using two strands of embroidery floss. But the floss is usually sold in six strand packaging.
So before threading your needle, you should separate all the 6 strands.
To do it just cut somewhat about 15”-18” (35 - 45 cm) of the thread. Hold it near the top with one hand allowing the bottom to untwist. Now pull each ply upward with the other hand. Carefully - one at a time.
Combine the necessary number of strands (typically two) and save the remaining for the next usage.

Before washing your cross-stitch project, just check the fibers for colorfastness to prevent dyes from running. It is simple: dampen a piece of white cloth with water and gently rub it over each different color in your piece. If there is any color transfer to the white cloth don’t wash your piece if you want prevent your work from discoloration and fading.
