The Sketch Challenge was pretty challenging to me to get all those squares to fit & trim off the angle at the bottom. At least it wasn't a tilted sketch...generally, I have a real problem handling those, lol.
For my 4 squares, I die cut 4 squares, left the die in place, stamped the smiley sun faces, used a reverse mask & sponged the yellow & oranges onto the suns. I used yellow & orange Copics to carefully color in the rays & edges of the squares, then attached them to ODBD lacey squares die cut out of turquoise. The white layer was die cut w/ a curved border. I used a lacy curved border to cut another edge along w/ a matching on in turquoise then attached them under the original cut edge. On the marigold layer, I partially embossed the Sunburst bg die then attached it all to a turquoise layer. The greeting was added on top of where the circle area is in the Sunburst bg.
