So, you have come to the end of your woven piece and now want to make another hem stitch to match the hem stitch you began with.  Here is how it works:

Step 1: You will be working from left to right, keep enough yarn for four picks across your work and cut the strand.  Thread the yarn onto a darning needle and insert the darning needle above the work, two strands over.

Step 2: Pull the yarn taught.  Bring the needle around to where you began and insert, bringing the tip through two rows down and two rows across.  This should make a wrap around the two strands of yarn that you are working with.

Step 3: Pull the yarn taught.

Step 4: Then, insert the needle before the next two strands, bringing the tip out two strands over.  Pull taught. This will make a verticle wrap around the two weft strands.

At the end of the hem stitch row, complete step one.

Then do step two except you will notice that there is no weft strands to hold the yarn in place.

This is where you weave in your end through the hem stitch by hiding the yarn in the middle.

The beauty that is hemstitch! You may now cut your warp!
