Since two years now I am climbing on my home climbing wall. On the initial setup I left some space for more holds. Those free corners have been filled up in the last months.
A few weeks ago a friend visited me for a session on my adjustable home climbing wall. Not only for me, especially for my friends it is sometimes difficult to remember the hand and particularly the footholds of a certain route on my home climbing wall. Unfortunately my home climbing wall has no LED system. But my friend had an alternative idea.
