Well it's nothing more than posting a photo every day, 7 days in a row, no commitments, no competition. You do it just for the fun, that's why I took part in the first place.
God! I'm waiting for vacations to begin as well! My last lessons are tomorrow (but unfortunately I'll have to cover up for a few lost hours during Christmas holidays).
It would be lovely if you finally managed to join the challenge, but you'd better focus on relaxing. Have a great Christmas sweetie! :)
