Today's them is education. I thought about doing pencils or paper (I had done that one before and thought I could do it better. . .). I saw some cute chalkboard nails. . . but honestly I wasn't excited about anything, until I saw someone do a design that was specific to their education. I don't remember who it was or even what they did, but they did inspire me to my education. I was a theater major in college and did a lot of musical theater. I have been in choirs since I was in 4th grade and have been taking voice lessons since I was a sophomore in high school. Music has been my eduction for a long time.
I thought I had a sheet music stamp, but I didn't. I did have Cheeky plate CH31 which I stamped with Orly Mysterious Curse. The background color is China Glaze Sweet Hook with Snow Globe over the top to give it all some sparkle. Then I did the stamp.
My thumb all alone. I had fun using the sheet music as a prop and background. Heehee, it was easy to pull from my collection.
All the other designers are sure to teach you a trick or two.
