Depending on how you both feel about practical gifts, cutting mats & blades for her Cricut are something that a regular using of their machine will go through fairly frequently so might be a good idea. I think Cricut also puts out a monthly subscription to a box of supplies which could be fun. Cricut also makes organizers for their tools and of course, there are other pretty/cute/cool craft supply organizers out there, too. If she has a favorite company or two that makes supplies (paper, stamps, embellishments) you could shop for those, often they put out a “kit” that includes all or most of the things of a particular line.
Etsy has A TON of embroidery accessory sellers with so many cool figural floss organizers and more magnetic needle minders than you could imagine! They also have sellers who make decorative embroidery hoops for displaying finished pieces. Here are two examples:
One of the best craft-related gifts I have every received was an Ott Light! It’s a full-spectrum lamp that makes crafting, especially on long winter nights, so much more pleasant and comfortable. They come in A LOT of models and styles.
