I had everything I needed, which is always nice. I used white fleece, pink felt, pink embroidery floss, and safety eyes.
I did a search on Pinterest to find ideas, and in the end I loosely copied something from an Etsy shop. (Please know that I would never copy someone's pattern to sell.)
We'll have to put the tooth in a little baggie though because I don't think the Tooth Fairy would like digging the tooth out from those long roots! ;-)
Right now the tooth is riding a horse, and has been named "Toothie".
