We receive at least a dozen envelopes full of junk mail each week. You can use these envelopes to make super bookmarks.
Step 1: Cut Off the Flap.
Cut parallel to the long edge.
Step 2: Separate Factory Corners.
Cut along the dotted line.
Step 3: Open the Factory Corners.
Snip off at a 45 so page corners can stick out.
Step 4: Mark the Margins
Put half a dozen pages in the factory corner. Mark the top and left margins so the text will show with the bookmark in place.
Step 5: Cut Away to the Margins.
Cut the top surface so the bookmark doesn't cover the text.
Step 6: View of the Back.
This picture shows the back of the bookmark.
Step 7: How to Use the Super Bookmark
As you turn pages, put them into the bookmark. When the bookmark fills up, take some pages out.
