The pattern specifies a size 5 steel hook, which is not available on Ravelry’s hook options.

This is a pattern for a long-sleeved tunic-style top for the Free Spirit Amigurumi doll, available here on Ravelry. Additional notions needed to complete this pattern are four 1/4” buttons (although you could use small hook-and-eye closures if you are unable to find small enough buttons).

Yardage may vary, but one standard ball of size 10 crochet cotton will yield several garments.
