hey!
so once she is in boxes (moving), you will come to my town and i will walk you to her house. you have to talk to her inside her house, and ask her to move in (as long as you have less than 10 villagers, you gotta have room for her)
then she will move in! thats pretty much it. after the trade, you send the tbt does that sound good? i hope i explained it good haha
