When I was making a latest model I had some problem. I needed to attach a thread to the mast inside a bottle. The answer may be interesting: I had attached a little loop on the mast and had made a little knot on the end of thread. Then I had weted the knot in liquid glue.( The knot will be more hard after drying). Inside a bottle, you can put the knot through the loop on the mast without problem. If you will pull the thread the knot will not fall out. For finish you must glue the loop.
