DIY trim/tank weights?

[redacted]

That seems kind of what I was looking to do. Where did you get the materials, LDS, local craft/fabric stores?

I bought webbing and velcro online (ebay) but you might try your local crafts stores. I used softer webbing than you usually find in weight belts but a softer weight belt should work. I used neoprene cement (used to repair wetsuits) but any rubber or contact cement should work.
