There are some good articles on the internet on how to carve and weight spearing decoys. It takes practice, but it's not that hard to make a working decoy.
You can also check out the Minnesota Dark House Spearing association website and the "Gathering" at Perham, Mn. where they show and score decoys sometime in April.
A good exterior latex primer and craft paints in small bottles work ok. Clear coat them with epoxy. Sheet aluminum works for fins and tail. You can either paint eyes or purchased molded ones to glue on before you clear coat. Lead for weight.
Although I don't spear, people have told me that a good working decoy will hang head slightly up in water and swim when lifted and let to free.
There are alot of good carvers with beautifull working and life like decoys, but they all started at the beginning.
thanks dude! that helped quite a bit.
