Buy embroidery thread at a craft or sewing store. It is much thicker than normal sewing thread, and comes in lots of colours. Pick 4 different colours of thread.
Take the first color and wrap it around your wrist 3 times and cut the thread to that length. Cut a piece this length from each of the other colours.
1. Tie the strings together with an overhand knot, leaving a 2" tail at the top. Tape it to a table.
2. Pick up strand A and wrap it over and under strand B to make a knot
3. Tighten the knot by holding strand B and pulling strand A up.
4. Make a second knot with strand A over strand B; pull strand A tight.
5. Drop strand B; pick up strand C. Make 2 knots with strand A over strand C. Repeat on strand D. Strand A will now be on the right.
6.One row has been completed. Continue next row by making 2 knots with strand B over strand C, D, and A. With each row, the strand on the left is always "worked over" to the right.
7. Four rows are completed. Continue until bracelet is desired length.
Start the next row using the string to the far left (green).Repeat all the steps until you have the row finished.Keep going until the bracelet is long enough to fit around your wrist comfortably. To make sure it fits well, try it on your wrist, there should be enough extra room that you can fit about 2 fingers in next to your wrist, since the bracelet can shrink in water and become too tight (although it will stretch back out when dry). Tie the loose ends of your strings with a square knot just like how you started the bracelet. Tie the bracelet onto your wrist (or your friend's) at the right length with a knot, like the first part of tying a shoelace, but do it twice. It helps if you can get someone to help you here, but it can be done alone.Trim any loose ends. You can also add charms or beads to the ends for decoration, simply slip them on the floss and tie a knot beneath them.
