Attaching Hair to My Crochet Doll Watch as I attach the hair to adorable crochet amigurumi doll! This step gives the doll the perfect finishing touch. I know this might be a hot take in amigurumi doll-making, but I used hot glue to reduce 80% of the time needed to attach the hair wig. The only downside is that the ends of each hair strand attached to the head may not be very secure when playing with the doll. That’s why I recommend sewing the ends of each strand to the head for extra durability.
