I think it's a bit too early for me to put the Christmas tree up. Traditionally we do it on the Christmas Eve,but mid December is a good time to start decorating for this beautiful holiday! However, I think it's a great time to start making Christmas cards now. The earlier the better!
If you send a bunch of Christmas cards maybe is best to go for CAS. But if you like layers,then maybe today's card will give you some inspiration to create something fun for your loved ones.
