Hi everyone. I'd like to try making soap on a rope. I searched the forum but I can only find posts from 2015. Has anyone used anything for a rope that I could find at my local Joann's fabrics? The posts I found talked about using hemp and I think polypropylene rope for boating? I'm not sure where I could buy either of those locally. Also, I wanted to use a silicone car mold. Would it be wise to put a hole in the bumper & thread the cord thru so that it will be embedded in the soap? I'm hoping the knot will stop the soap from leaking out. Any suggestions are welcomed.
