Studs are great, you can just leave them on the car and forget them for the winter. But PLEASE, do NOT go making your own studs, at least not any car that is going to be driven on a regular basis on roads.
i know you can not drive studs on the roads around here... and chains are really just a temp. thing for mountain driving etc.. i don't think you would want to leave them on all year. just get some snow tires. if you cant make it down your street, you shoulnt be driving that car in those conditions! :P
