I printed the front/back cover in colored printer paper and multiple copies of the inside pages in white printer paper. Then I used my paper cutter to cut the inside pages in half.
I folded the front/back cover in half, inserted the inside pages, and stapled them together along the fold.
Then the kids can document our summer fun on the pages - where we went, who went and when we went - and draw a picture of the what we did on the field trip. For little ones, you can print out a photo from the day and tape it to the paper.
I have a some summer-y stamps (flowers, sun, butterfly, etc.) that I'll use to stamp the back of the page (like getting a stamp in your passport) once the girls are done. My kids still LOVE stamps!
