Does the friend know abt the other gift or your situation? You can do a card and decorate it and write there how much they mean to you and everything or you can like craft something if you want but I`m sure they will appreciate it no matter what!! You can also tell them that you really wanted to make something better but couldn`t!! If they really care abt you they wouldn`t mind the gift you give but think that the most important thing is that you came there!!β€β€
