Edgie-Wedgie Ski Teacher - Edgie Wedgie Ski Teacher for Beginners: This inexpensive device is the best money you will spend if you want to teach tots or other beginners how to ski! With the thumb screw on the bottom of the ski, the Edgie Wedgie attaches to both skis and keeps a beginner's skis from separating -- instant control, easy to use. The strap can be shortened as needed. These are easily put on and taken off. Note: Obviously, beginners need lots of supervision. Tots learning to ski should always use a harness with an adult skiing right behind . . . Select a gentle smooth slope until your child is ready for more. Always remember: Safety first!
