If you really want to appreciate your friends for their help, then you should consider sending a sincere handwritten thank you note. In your note, write what you’re thankful for and let them know how much their help means to you. You can also show your gratitude to them by saying “thank you” when you meet them. Another creative way to appreciate your friends is to include gift cards inside your greeting card. Whenever you’re having difficulties choosing the right way to show appreciation, simply get your friends a gift card so they can treat themselves well.
