I know how you feel. I have been moving plants out into the garden too. Remember to protect any little seedlings from birds and other wildlife. I had to start my entire annuals garden over after (I'm guessing) the birds ate all the little seedlings! I"ve been using plastic cups with the bottoms cut off for perennial seedlings out in the main garden area and that works good. They start growing out the top of the cup and then I remove it!
