Christmas music mittens

I've just finished a Christmas present: Anne Neumann's fingerless music mittens:

The pattern is free, and is found here, both in German and English. The pattern gives instruction for a medium woman size. I added 5 sts in each side to make them fit a man's hand. I wonder if they're a little big? We'll see. I used white Juvel (which is super wash, so I can't hope for shrinking) and Kauni Effektgarn for contrast (which certainly shrinks... not a good combination, maybe). Anyway, I like the result, hopefully the receiver will too.
