A Celtic Knot Wall Decor or a Celtic-themed book, such as "Celtic Myths and Legends" by Peter Berresford Ellis, would make a great Father's Day gift. Additionally, you could consider gifting him a traditional woolen Irish sweater or a piece of Celtic-inspired jewelry, such as a brooch or pendant with Celtic knot designs. Alternatively, if he enjoys whiskey, a bottle of high-quality Irish whiskey with Celtic-inspired labeling could be an excellent choice.
Or you can get him a star map with the date when he welcomed you in this world.
