I use this product for craft patterns and instructions articles I want to save and recipes off the internet. It protects everything I want to save. I put everything in three-ring notebooks.
Our family uses sheet protectors to keep samples of work pictures certificate and programs from the school year in a notebook. As Homeschoolers in Pennsylvania we are required by law to provide our school district with samples of the work each student did each year but our family makes them as memories to last forever and the sheet protecters help us preserve them.
I bought this product to clean up and organize my paperwork at home. It's easy to open and slide papers in (even papers that shouldn't really fit) although if I accidentally turn over the binder they're in sometimes a few papers start to slide out. It's also a bit difficult to place these in the binder if you're holding more than a few (because they slide so much that it's hard to get the holes to line up) but otherwise it's a great buy at a great price. Definitely worth the money.
I utilize these Document Protectors in my One Stroke Painting classes. I insert worksheets and then the students practice painting the strokes provided on the worksheets. They can wipe the paint off repeatedly and keep practicing as long as needed. They can store the worksheets and syllabus for future reference when finished with the particular project. I should have purchased the non-shiny sheets as they don't have such glare from the classroom lights and will do so next time. Other than the glare of the clear sheets these are very applicable to our need.
