Hi Rachel!
Adding words to pictures can be so fun! You might find the last four of the replies on this forum discussion helpful😊 https://www.lenspiration.com/forums/topic/lightroom/ \
I use the free version of Canva (https://www.canva.com/) all the time, and if you do decide to use it, I would be happy to walk you through uploading your photos and adding text if it’s a bit daunting at the start:-)
Hope this helps!
Laura
