I use square knots often in class projects and I had a whole group recently that had never done one before so I thought I would make a very fast video tutorial. When I learned to tie a square knot in Girl Scouts a zillion years ago, we learned the mneumonic “left over right, right over left” to help remember the steps. In a class I took a few days ago she said “short over long, short over long”. Both of those work great!
Think to yourself “left over right, right over left” or “short over long” as you watch my hands tie the square knot in this video.
