Hi, you can also use a 'jack line' This is a tensioned line at the back of the mast about 1/16th inch out and can be held in place with small split pins, mast drilled and glued to hold them in place. You can use thin piano wire for this as well.
Simple hooks from hook and eye use for the sails. Or use 1/2 inch lengths of white plastic tube held to the edge of the sail with adhesive sail cloth.
I have used this system 2 or3 times and it works well.
Oldest one about 10 years old and no sign of wear.
