Felting with noro kureyon

I am making felted boots for my cousins baby for her first birthday.

As I have never felted anything that has a danger of felting together, I am wondering whether I should put something inside the socks.

If I stick them in the washing machine just like that, will they felt so much that they won’t open?

Awww those are so cute! I don’t think there is a problem with them felting together. When you take them out to check them open them up each time.

Cute!! You shouldn’t have a problem felting them together.
