My daughter is three years old. She's old enough to help make a softie. Though she's too young to work a sewing machine or use a needle, she can stuff and help choose out fabric. And at this age it's all about, "me try!"
Making a toy with her is a whole new level of sewing love. If you have a little one at home, give it a try. Not only will you have a wonderful memory to cherish, but they'll have a new toy to play with, one that's handmade with love.
