It is tempting to stitch for hours at a time, especially when you can make the time and when you get in the "stitching zone." It is important to avoid this temptation, especially when you are a new stitcher. Taking breaks helps to prevent repetitive stress injuries and eyestrain.
Stop stitching, get up, stretch, rest your eyes and hands for a moment, and then start again if you like. If you have trouble with "getting in the zone" and forgetting to take breaks, use a timer. Use the TV schedule or musical selections. When the buzzer, show or CD stops, it is time for a break.

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.
