I would like some advise on adjusting a mold I have already. I am looking for a product to change the way it is formed by closing up one of the sides.. I have a flag mold that is too thin for my purpose so I need to double the 2 and make one single one like a shell. Please suggest how I can close up one of the balls of the top of the flag pole to make it disappear.
When asking questions like this, photos of the mold will help us visualize what you're trying to achieve.
