This is the most complicated friendship bracelet. You must do this one with four colors/eight strings. For this one, you definitely want to measure longer strings – for medium-tightness or loose knots, use your “wingspan” as the measuring point for this. You can go a bit shorter than that for tight knots.
Order your colors in order – for example, red/red/blue/blue/green/green/yellow/yellow. Make five forward knots with the first string (red number 1). Make four forward knots below that with the second string (red number 2). Make three knots below that with the third string (blue number 1) Make two knots below that (blue number two). The string order should now be green/green/blue/blue/red/red/yellow/yellow. Now, do the same thing backwards (with backwards knots). You should use yellow 1, yellow 2, red 1 and red 2. Your new order should be green/green/yellow/yellow/red/red/blue/blue. Continue working back and forth with the 5-4-3-2 pattern until you are done.
