I shared this map art that I made for my brother and SIL on this blog post.
This was the inspiration piece:
For theirs, I chose to print the three states that they have lived in together.
I found my maps online (just Google search “Texas Reference Map”, or whatever state, and choose one that is a large file with high resolution) and just printed them on photo paper.
I cut little hearts out of some red glittery cardstock paper using my Silhouette Cameo and just pasted them over the cities that I wanted. Then, after I carefully cut out each state, I placed them between the two panes of glass for this floating frame that I picked up at Michael’s. I taped the back side to the back glass pane so that they would stay in place.
These are some other variations I’ve made:
