This is off topic but since you are all such talented artsy folk I thought I would see if you could help.
I am looking for some type of inexpensive but sturdy art case. My kids are in a homeschool co-op class for Art. They also bring home art from Sunday school and create tons on their own. We display current masterpieces but I want to save what is currently not being displayed (which is growing quickly). I looked for cases and portfolios and most of them seem for the serious artist and cost $60+ dollars a piece (I need three!) I did find a cheap papery cardboard on that was only $8 but wouldn’t last.
