Okay - so it seriously took me hours to figure out how to use the Coffee Shop rounded corners collage template in Elements (I use version 7). I read a few of her tutorials and fiddled with it for awhile.
So I thought I'd share my process here, hopefully it will help you if this is something you're struggling with.
Step 1: Open the .psd template in Elements. Drag your numbers to the background (or turn the layer off)
Step 2: Drag your pictures onto your workspace.
Step 3: Adjust your layers so that your photos are on top of the corresponding cut out shape.
Step 4: Here is the trick: select your photo, hit ctrl+G and adjust within the template.
Step 5: To add a color box: add a solid color layer, drag it in your list of layers on top of the shape you want and hit Ctrl+G
Step 6: Add text!
The template is from The CoffeeShop and the font for my "project 365" is called CK Becky, the font for my numbers is called Courier New.
