A great anniversary gift idea for your girlfriend could be a beautifully designed origami kit. The kit could include numerous colorful pieces of origami paper, a detailed guide book with step-by-step instructions and diagrams, and available templates to make various shapes and models.
You could also get a set of books on advanced origami techniques or even an online class subscription to further hone her paper folding skills. Alternatively, you can exploit her interests to create little touches of romance such as making origami flowers and turning them into a larger bouquet or designing small origami figures as thematic centerpieces.
Or you can get her a star map with the date of your anniversary.
