I keep meaning to share this idea.
When kids are young and want to embroider with you, but have a tough time because their motor skills are not quite ready for a small needle yet, try burlap embroidery. My son loved it when he was younger and older kids can have fun creating designs too.
We used burlap stretched in an embroidery hoop and a large blunt end needle with yarn tied on to the eye. So, no constant re threading. It is a great project to have tucked away when you need to keep little hands busy for a while.
