DIY Toothy Plush Monster Costume: 40-Min Felt Build

A fuzzy onesie with tall ears on the hood and a huge grin of white felt teeth across the chest. The cuddliest monster in the room. Forty minutes, easy: fuzzy one-piece pajamas or a sweatsuit, white felt for the teeth, and felt for the ears. The teeth should be oversized and goofy; neat little teeth read as cute, big ones read as funny.

DIY this week: 40 min of hands-on work

Fuzzy one-piece pajamas or sweatsuit, 1 (buy: thrift store, or own: from closet)
White felt for the teeth, 1 sheet (buy: craft store)
Felt for tall ears, 2 pieces (buy: craft store)
Keychain ring or carabiner, 1 (buy: dollar store)
Fabric glue, 1 tube (buy: craft store)
Scissors, 1 pair

Tip: glue two smaller teeth to the sleeve cuffs as claws. Teeth on the grin plus teeth on the hands sells the mischief.

Steps

Cut two tall ears from felt and glue them to the hood, angled slightly outward.
Cut a row of big triangle teeth from the white felt and glue them in a grin across the chest.
Safety: use non-toxic fabric glue, keep small felt scraps away from toddlers, and let everything dry fully before wearing.
Clip the keychain ring to a belt loop or the onesie zipper pull like a collectible tag.
Pull on the fuzzy onesie and fluff the ears upright.
Optional pro finish: glue two smaller teeth to the sleeve cuffs as claws. Teeth on the grin plus teeth on the hands sells the mischief.
