Icing cookies ( Biscotti glassati) second try.

This is not a recipe post but a "show off" about what I made this week end, taking inspiration from Pam ( http://cookiecrazie.blogspot.com/ ).
I've piped them, unluckly I have only one sac a poche so I can manage just one color at time...It's not so comfortable, next time I'll try to have more material to work with.
It's quite easy once you take confidence with icing but it's a long work!
