Since I only had Red, I made the rose first, then made a red stem. Later, I gathered more colors to finish the look.
So, I decided to beg others for colors to complete the stem & thorns. Below is the final result.
So, all-in-all, I think it turned out pretty good. Several co-workers told me to leave it out and let is harden, but then I wouldn't have any more Play-Doh to play with, so in the end, I wound up destroying it.
