This pattern can be used to make all three Powerpuff Girls.
Each doll stands about 10” tall

there is no gauge info.
I have recommended yarn and hook size but the dolls can be as big or as small as you choose depending on the yarn weight and hook size you choose to use.

You don’t need much yarn for the dresses so you might be able to get away with destashing to make one or all of these dolls.
