One great gift idea for your friend who loves glass etching could be a glass etching kit! There are a variety of different kits available at different price points, depending on your budget. This would allow your friend to create their own etched glass designs, and it may even inspire them to try out some new techniques and projects.
Another option could be a set of personalized etched glasses. You could have your friend's name or initials etched onto the glasses, or choose a design they would appreciate. This way, your friend can enjoy using and displaying their custom glasses for years to come.
Lastly, you could consider booking a glass etching workshop or class for your friend, where they could learn new techniques and get hands-on experience creating their own etched masterpieces. Many art or community centers offer glass etching workshops, so you can check out what's available in your area.
