This activity works for me for a long car ride or a long wait.
Use a piece of sand paper (8 1/2 X 11) and yarn (different lengths) to create different designs/pictures on the sandpaper. The yarn sticks to the sandpaper, but you do have to press it down. I cut the yarn in different lengths ahead of time and put them in a small bag.
To make this into a file folder activity/lapbook, staple the sandpaper to the front of a manilla folder (staple the folder shut on 3 sides) and inside the folder keep three bags for yarn (short pieces, medium pieces, and large pieces). This will keep your activity organized and cut down on the yarn that spreads out around the car or waiting room. This is a great activity to add to a Busy Bag!
