Horse themed gift basket with a bunch of little things? Put in polo wraps, some new socks like you said, new brushes, some treats/cookies, a coloring book like this (https://www.amazon.com/Horse-Pony-Coloring-Book-Equestrians/dp/B0C1J7CSDL/ref=sr_1_11?qid=1681780404&refinements=p_27%3AEllie+Eve&s=books&sr=1-11&text=Ellie+Eve) ?
How about a coloring book! Will be great to transport in a suitcase too
