First step is to roll all of your fabric flowers. I used this tutorial found at made by the mama monster.
Next, cut felt circles and hot glue them to the back of each fabric rose to give it more sturdiness.
Cut a cresent shape out of your felt which will be used as your base for your fabric flower necklace.
Arrange your flowers on the felt to create a pattern that is desirable to you.
Take your glue gun and glue down all of your flowers to the base piece of felt.
The back will look something like this. Not perfectly beautiful but no one is looking at this side.
Lastly, take your piece of necklace chain and hot glue to the back. Then glue a felt circle over the chain to hold in even more securely in place. Make sure that the chain is long enough so that the necklace can fit over your head.
