I agree with QuiltE, if this quilt is for you it will be a nice way to remember the memory.
But as a funny thought, the last time I went to Disneyland, I was in the restroom and noticed the hexagon floor tiles, and liked the design (a very basic GRG) but I liked it, so took a picture of it. (I was a bit concerned because I thought if anyone heard the phone click they must have wondered what the heck I was doing. But that was easier than explaining to others why I was taking pictures of the floor with a bunch of people watching.) So for me I would have the write: Inspired by the tile patter on the floor of the bathroom in Disneyland on April 28, 2016."
