I recently purchased a poster (movie poster size) for my class. I was hoping to have it laminated so that it lasts longer... and then I found out today that Staples can't laminate it for me! It's too big! They told me that all the other copy and print stores have the same size laminater. Has anyone ever had this happen before? Any suggestions for a place to go or an alternate way to protect this poster (I have concrete walls, so getting a frame and hanging it won't really work). Thanks.
