Use 2 of the 6 strands in the floss. Both go through the eye of the needle. Make sure the end that went through the needle is left free when sewing. That way you are only using the 2 threads. Also very important make sure you have all the threads going the same direction. I go left to right then double back to do the top of the x. I start coming up from bottom of cloth and bring needle to the upper left of x, then down through fabric in lower right of x. I do how ever many stitches for that color the go back to make the x. Start at upper right and go left down through lower left of x. How you do well. It really is simple. wish I could show you.
