Head and body crocheted as one piece, crocheted eyes with 2mm hook. The helmet resulted a bit large. For hair I used the suggested method with same yarn as body, using a plastic piece of cm large and cm long, worked for entire lenght then sewed in wide zig zag shape from one ide of head to the other to prevent the “lion” hair I obtained with Thor (using two and a half more of hair).
Used a crocheted chenille stem for scepter.
