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:
attaching button eyes to the face of a medium/larger doll
jointing arms & legs to the body of a medium/larger doll
creating indents to shape larger items such as pumpkins
