There is really no big tricks to this card however if I were going to pick out things to take away from this project I would point to the coordination. The DSP (designer series paper) is all neutral black gray vanilla. I added a pop of color to this DSP and it really made this card. I used Watermelon Wonder, this color is very interesting because it is not orange, not red, not pink sort of coral and it seems to adjust to what you put it with to some degree.
The next thing I would point that makes this card a tool of learning would be the black mat. When working with DSP especially one with a geometric pattern a solid mat finishes off the pattern visually. In this case the stark black punctuates and pops the whole card. Taking the few seconds and few pennies in material to mat is so worth it. If this panel wasn't matted this card would be blah and ambiguous. Instead I really like what I made and frankly it's one of my favorite cards I made this year. That says a lot about a really very simple and easy card. Layer layer layer.
