finger foods?

Ashley
Hey Mommas! 
My son is 7months, I've been giving him solids for alittle over a month and he's doing great! Now I've read that we can start introducing finger foods if he's showing signs that he is ready.. like the pincher grasp which he does, and he has also mastered sitting up unassisted which seems to be the only position he wants to be in now! 
My question is have any of you moms started finger foods yet? And if so what are you giving and how is it going? 
As a first time mom I obviously have a fear of choking so your advice would really help me and put me at ease!
