I have a hard time with pages like this when I sort of have a several page theme going, but don't really have any pre-made stickers, titles, or anything that fit the theme. I think that the CM basic layouts with the "shortcuts" stips of wavy paper and triangles in maybe blues, aqua, or varying shades of green and brown might work for a coherent theme throughout the book. They'd be generic enough to go from beginning to end without detracting from each phase of the process. If you wanted to dress it up a little bit, you could use the punch shapes (squares, rectangles, circles) and stickers for each phase to say something like "STEP 1 ...dig a hole". I probably wouldn't try to incorporate artwork unless you had something like cute stick people wearing hardhats doing the appropriate work and have those those little balloon thoughts coming out of their mouths. I also think these stickers would be cute on the pages if you embellished them.

I don't envy the pool process. My family built one when I was in high school. We did everything ourselves except dig the hole. It sounded fun for a while and then we learned we had to clean it everyday. Now that everyone has left home, my dad finally bought one of those vacuums that you can plug into the filter system so you have to manually vacuum.

Good luck.
