The possibilities are endless on creating with this tool..
ADD TWINKLY lights to semi clear boxes for a vibe inspired glow

Which height do I want Center
I personally collect all my clients details, and then dump the boxes out and start with what I want in the center. I usually make that the tallest so I play with what box height I want with their smaller details.
