Here is the side that my daughter designed. I let her choose the paper, then I cut it to fit. I also cut out the frame details that she wanted from the papers. She chose the elements and arranged them the way she wanted. She also stamped the 'thanks' sentiment and glued the smaller pieces to the large panel. This way she felt like she got to take part in the creation, but all the sides sort of match.
Here is a side view that shows two of the panels at the same time
and here is an up-close of the two Joy's Life stamps that I used. This one is from the Holiday Occasions set.
And this one is from the Tag You're It TWO set.
There are a lot of tutorials for these flowers out there. This is the one I used. Although, as you can see, I didn't follow the color guidelines like she suggested. We used every color - orange, pink, yellow, blue and purple. The blues and purples didn't turn out very well though. They look pink and white.
