I am pleased for him because he worked hard to get it -- even though I have no desire of my own to be painting miniature bits!
Meanwhile I'll be there sewing something interesting for the child and he will look when I say "Look! I got this difficult seam down. HA!"

He's pleased child will get whatever kooky it is she asked me to make her. He has no desire to sew on his own -- but he admires the effort and is happy we are happy.
