How about a soap-making kit that includes all the tools and ingredients needed to make her/his own handmade soap? You could also include a special fragrance that you think she/he would like or a book on soap-making to give her/him more ideas and inspiration. Another idea could be a personalized stamp with her/his name or initials that she/he could use to mark her/his handmade soap creations. Lastly, you could also consider getting her/him a subscription to a soap-making magazine or an online class on advanced soap-making techniques.
Or you can get her/him a star map with an important date you share.
