I finally understood why my sand molds kept crumbling

I was casting a small decorative piece at home last month. Every time I packed the sand mold, it would crumble when I removed the pattern. I tried adding more binder, but that made it too hard. Then I recalled a chat with a veteran caster about sand moisture. I tested different water amounts until the sand felt just right. The next mold held together perfectly, and my casting came out smooth. It's amazing how such a small detail can fix a big problem. Hope this tip helps someone else with their home projects.
