This project is really simple and you only need 2 materials.
1.an old necklace chain ( if you don't have one you can use a string or elastic)
2.a handful of safety pins that are all the same size ( I think it looks best to have them the same colour as your chain)
Step 2: Start Threading
Start to thread all of your safety pins onto your chain or elastic. Thread them through the small hole in the bottom and not through the bigger space. Continue this step until you are finished.
And there you have it! Your own unique safety pin necklace!
