Sorry I don't post here much... I lurk sometimes, but usually don't have a ton of time to post with my two little ones. Anyway, my youngest is going to be 11 months old tomorrow and I'm trying to plan some cute cake smash photos to take in a few weeks for his first birthday, and I love the ones where the floor looks glossy/shiny. I'm just wondering what materials (like plexi-glass or something?) work best for this, and where to get them? Also, what size is best? TIA for any advice!
