I've seen this picture on the internet several times now and I really love the idea that you don't loose the grasp on your tiny person's hand with these cute mittens.

So I searched for a shop where I could actually buy those hand in hand mittens, and this is what I found: you can buy them here (Forget me knot mittens).

I imagine you could even do them yourself, but unfortunately, I don't know how to knit.
