Square - Box - Stitch - Doing the stitch

Now that you've done a starting stitch. We add a left strand, a right strand, a top strand and the bottom strand. Take the left strand and bring it over to the right. Keeping it straight. Take the right strand and bring it over to the left, keeping it straight. My top strand sits on the left side. So I need to keep it on the left side, going over and under those two loops. My bottom strand is on my right side, staring to keep it on the right side. Going over and under the loops. Once you've done that, just pull on all four strands and make a really tight stitch. So again, you take the left strand, bring it over to the right. Right strand, bring it over to the left. Now my top strand is sitting on the right. So you need to keep it on the right and you go over and under. My bottom strand needs to stay on the left. Go over and under. Keeping it straight, and then pull. To make sure the stitch is really tight, and just keep repeating this until you're ready for the final stitch.
