How to tie the Friendship Knot
Step 1: Hold your scarf flat, red side on the left.
Step 2: Roll up the scarf four or five times to make the ends narrower, more rope-like.
Step 3: About four inches from the end, cross the green end underneath and back over the top of the red.
Step 4: Hold your finger on the red end at the crossing and wrap it towards you, underneath.
Step 5: Pull the red end up over the top of the green.
Step 6: Pull your finger out of the red loop and push the green end over the red and through that loop.
Step 7: Pull the green end all the way through and tighten as needed to get an even square shape.
