The sheet protectors are necessary for a couple of ongoing projects I am currently involved in. The first is putting together a loose leaf binder of old family recipes for my grandaughter who loves to cook. The second project is to photograph my completed paintings (I am a professional artist) mount them and insert the page into your page protector and place in a loose leaf binder. I have been doing this for many years and your page protectors are an important part of this project of catalogueing my work.
