I finally got off my duff and here it is!
These are my Bent Nail Crosses.
Here's the thing. These nails are a pain in the rear to bend. You over bend and they snap when you try to fix it. You under bend and the cross doesn't line up right. I have gone through an entire box of nails to get four nails. Practice makes perfect, though.
You could also buy them pre-bent. Look for prebent disciple cross nails.
There are a ton of tutorials on how to do this. The way I do it is a tad bit different than most tutorials I've viewed. It's easier for me this way. I also shuffle cards backwards (with my thumbs, not my fingers) so this might just be me.
I always start with the two nails that will make up the bottom of the cross. Start wrapping your wire around the nails to hold them together. I use a clamp to help.
Finished! This does take a bit of practice so make sure to use cheap wire to practice. I like the colored aluminum wire. . . it's soft and cheap. Thread a cord through the top and you have a nice necklace to wear!
