Can I see a pic?
Nothing to it. Small snap shackle clipped around forestay above the upper hank (I do the one below as it seems to slide better), turning block at deck level, and run the cord along the deck back to the cockpit. Cleat the end. Only complication is it needs to run free when hoisting, so a rope bag to store the tail end is useful.
Once down I pull the sheet tight, as this helps to hold the sail in place. If you dont mind a quick trip to the foredeck, a sail tie around the body of the sail and the pulpit or lifeline completes the picture.
