You could consider buying your girlfriend a pair of tickets to a folk music concert that she's been wanting to go to. Additionally, you could add in a gift card to a nice restaurant near the venue and offer to take her out to dinner before the concert. Another thoughtful idea would be to create a scrapbook of all the times you've spent together while listening to folk music or attending concerts. You could fill it with concert ticket stubs, photos, and memories of your favorite moments from these special experiences.
Or you can get her a star map with the date of your anniversary.
