This appears to be a pattern only so you will have to buy material and thread to complete it.

Not stamped. There is a section on the home page (main page) called "Stamped Projects & Stitchables" It will take you to stamped items, but many many stitchers have switched over to counted cross stitch.
You could search/google for stamped Cross Stitch Christmas Stockings.
I am not an employee of ECS, just a stitcher in this chat.
