Yes, yes - a keyhole scarf - I guess that is what you call it lol I've seen them a few times but didn't know the name. It allows you to have the scarf secured somewhat without actually having to tie it
I'll see if I can find a picture of what I am trying to describe.
And again yes, yes to the chain - I am pretty sure somewhere along our walk DD got sick of the mittens and slipped them off. If she had had a chain, they would come off her hands but just hang and she wouldn't have lost them!!!
That Etsy set is so cute - that is where I bought her mittens before -
again - and they cost about as much
Her hands are pretty small I think - she's only 2 and is a bit smaller than average I think
What kind of mittens do you have??
