This is awesome when I was meddling with my necklace and some safety pin while I found out that my pendant can be a pretty brooch!
Get a pendant and a safety pin
Insert the pendant into the safety pin
Slide it to the other side of the safety pin
Pin it to your shirt and you're done!
LOL you're right it's simple ,love it.!!!
put how did you do the slinding on the cirled side or the other?
