They are DIY keychains
And then use the colored wool thread to wrap it right around the tongue evenly. And so create a round shape. Then continue working the wool so as to create what looks like the body of an animal of which you have already made the head . And with a glue gun fix the wool thread so that it does not unravel.
And after you have formed the sweet head of this animal, which is an octopus , you can continue by creating the body with the wool thread that you work always starting from the base of the head. Form the tentacles and make them in the way you like. Then you can apply the eyeballs to make the animal more recognizable. We recommend using stickers. Now you can take any ring of a keychain and always attach it to the tab of the can, which was used precisely to give the shape of the head to the octopus but also to easily attach to any keychain. And in this way you will have created a truly unique DIY object, which can be part of the context of a creative pastime, but also of a business strategy.
