She used the pin in the pic. below and three threads to make it thick.

My little sister is always doing something with her hands. She's either knitting, making a bowl with beads, key holders,painting a picture, drawing,sewing, braiding someones hair(preferably a dolls hair)....whatever she finds interesting.  I'm always proud of her creations. She's in her early teens now but at age 6 she could braid her dolls hair (from watching me braid) and knit pot holders better than me. Lets encourage our little ones to develop whatever it is that comes naturally to them.
