I cheated...I took one of the tips from my cake decorating kit no longer being used, and taped that tip to the top of the glue bottle. That worked great for my first project! And then I realized, how do I close the tip and keep the remaining glue from drying out in the bottle? Off came the tip and easy came the closure of the glue bottle! The tip is on stand-by, just in case needed in the future.
