Collage will send you a confirmation email when you place your order and another notification email when it ships. If you want to check the status in between that time, sign in to your Collage account (or create a Collage account with the email you used at checkout) by clicking, and then Your Orders.

This will bring up your order list to view the status: 

Here you can check the status, cancel (if applicable), buy it again, verify the shipping address, and check tracking if applicable. 

If you cannot find the menu button, click three lined button in the upper lefthand corner and then You Orders will appear. If it says Sign in, you'd need to sign in first to view.
