A couple of years ago, I did something similar with etching sand and some drinking glasses. My glasses said, "Keep Calm and Drink Beer". I gave them to my dad. The glasses were in a set of 4 from Target that looked like this. Then I used my Silhouette Cameo to cut out a stencil and I used etching cream to finish it off. They turned out great. Sadly, I didn't take any pics.
Last year, the boys made Daddy a Father's Day gift of their handprints. It was super easy and free! I had everything I needed to make this, so it was super simple. You can see the how to's here.
I also thought about boudoir photos and looked some up, but thought they were too racy to post a pic of an actual photo. I'll just link it to some I found on Pinterest.
