First, gather everything you'll need so you don't need to look for stuff later. Measure and cut the lace and ribbon so that it is just a bit shorter than your neck.

Put the ribbon face down and put glue on it. Carefully stick the lace onto the ribbon, making sure that the lace is completely flat against the ribbon.

Leave it until it dries completely.

Attatch this thingy to the ends of the ribbon. I can't remember the name of it. Sorry

Attatch a lobster clasp to one end and chain to the other.

And you're done! Enjoy =]

You can wear it with the ribbon on the outside or inside, it looks good either way
