Quick and easy solution is to tie a loop of line through your reefing point. This loop will hang down far enough and can be put through your reefing hook. Basically it's a poor man's dogbone and quick to rig up. I put them on my mainsail while underway in order to make reefing quicker and easier.
A fisherman's bend is a good know for this and 7-8mm cord would probably be a good choice. You'll have to experiment with the length a little.
