Spoons are a great alternative for making pad weights. I've used a big old metal camp spoon for this very purpose. You'll want to put some candle black on the inside of the spoon and then heat it up on a camp stove before you pour the molten lead into it. Be sure to do this outdoors on a dry day as the fumes can be very bad. I usually spray or dip the weights in plasti dip to prevent marring or rubbing on other decoys.
