This can be for a youth fund raiser or gifts for a special occasion, such as Christmas, or Awards. Buy some 2 inch old fashioned cut nails at the hardware store, some thin copper wire and have youth make crosses out the material. It will take 3 nails per cross and about one foot of wire. Cost, around 5 cents each. You can add a fishing swivel, and lentel material for necklace. Tthis is a great project and can be sold for as much as $10.00 each or can be used as gifts to others for just pennies. They can also be placed in gift boxes (found at your local jeweler) with a little description and explanation of the cross for an added touch.
