I made this necklace a while ago this summer thanks to the wonderful demos at this great bead store in my town. It was fairly easy to make and took no time at all. I have made several variations too. Some with back of the button holes for a choker and an all blue one. here it is.
I have a tendency to get too wordy so I hope this works for you guys. These aren't the best pics either so if you have any questions just ask.
1) Pull about one foot of wire (depending on the amount of buttons) through one hole of the button that will be in the center.
2)Now pull the wire from the front around to the back and pull through to the front again.
3) Now place the next button behind the first one. Bring the front wire through the next closest hole (on the second button) to the back and bring the back wire through the same hole to the front. NOTE: You will always have a piece of wire coming from the front of the row of buttons and one coming from the back.
4) Bring each wire on either side through the next hole so that the wire that was in the back is now in front and vice versa.
5) Keep this process going with the next button and so on. In the end you can attatch ribbon, chain, cording, etc. I just kind of tied my ribbon through the wire when I got to the end and twisted the wire so it wouldn't come of.
Repeat these steps on the other side.
