I love all of these projects!! I need to make one of those laptop cases for sure. :D
The pillow out of plastics kinda reminded me of when I was in scouts, and we made "sit upons," which was basically a project to take camping for when the ground was too muddy or whatever, they were mats for sitting upon. The inside stuffing was newspaper. I still have mine, so that means I have mid-1980s New Jersey newspaper in my apartment, ha ha.
