Piecemakers® needles are my "goto" brand when creating dolls and crafts. They have clean eyes which makes them easy to thread, they are sharp so they can pierce through the fabric with ease & are strong and sturdy which means they'll last a very long time.
A few suggested uses:
sewing doll hair to the head
attaching button eyes to the face of a smaller doll
jointing arms & legs to the body of a smaller doll
creating indents to shape smaller items such as pumpkins
