Here is my Loads of Love Truck Book that I made for my four year old son. Needless to say, he loves it! This is really simple to do and I will show you all the pictures in it below. All I used is the Loads of Love truck stamp and a marker to make the additions. I colored them in with lots of different colored stamp pads and the Blender Pen to give it that watercolored look.
First, just stamp the Loads of Love truck on a small piece of white card stock or watercolor paper. I used just plain white card stock. All of these trucks have the full truck stamp stamped, and then the additions were made. The book is just Pumpkin Pie card stock stapled together and then the ribbon put on over the binding.
Then, for example with the fire truck, I just used a black marker to add the ladder on the back and the light on the top. (Later I also added a horn on the front, but not in this picture.)
