You might have to "tighten him up".
Something painful, no doubt
It seems like the knot tying is the problem...perhaps having him practice and/or draw how to tie several of the more useful/necessary knots (which he can get from any good bondage, surgery, or camping handbook) one hundred times each would be a good task. Then he could complete a "final project" to illustrate his newfound skills. :[

Of course, as a sub, I'd probably get a perverse enjoyment out of such a task so I guess it depends how much you want him to enjoy himself.
