Creative Writing Ornaments

This lesson's focus is about how to write very detailed descriptions.  The process:
1) students are given a photocopy of a large circle on white paper, the rest is blank
2) criteria for step one: decorate your ornament using only shapes and patterns (no drawings/words) must have at least 3 colours used and no white showing, do not put name on it
3)write a very detailed description of your ornament.  I have modelled examples of detailed vs not by saying "a girl in class, who is it" not enough info so add details, brown hair, glasses, wearing a red shirt, etc and they easily guess who it is
4) hand in the two papers that you have been keeping hidden from prying eyes while creating
5) number all the ornaments with large felt from 1-27 in this case for number of students participating and display them clearly on the front board
They have been mixed up at this point and no one knows who each ornament belongs to.
6) hand back written descriptions to the owners and have them list the numbers 1-27 in the margin on the back
7) each student takes a turn reading out their description and the rest of the class attempts to figure out which ornament is theirs and write that person's name beside the corresponding number.  The goal was to write your description in a way that it would be easy to guess because it was so detailed and clear!  Read each description twice giving think time between
The students show they can be amazing attentive listeners during this activity.  It is a "contest" to see who can match the most ornaments correctly from the descriptions.  I awarded little prizes at the end.
8)exchange guess papers and reveal time!  Go through each ornamnet and find out who it belongs to, students mark, total it up and you have a winner!  24 correct in this case.
I asked the students for their thoughts about the activity, some of the comments were: they definitely enjoyed it, thought it was fun, they were engaged throughout.  Creating first helped them get more details down when it was time to write, hearing all the descriptions helped them decide what kind of details were important and different ideas for how to write them if they were to do something like this again, helped make a picture in my mind.  Frustrating when peers presented not enough information or not clear lacking detail.
Think I need to do a similar activity for a follow up to see if their descriptive writing improves further now that they've had this experience.
