The paper size must be the same as or larger than the binder or notebook. If it’s larger, measure and cut to size.
Use contact paper. Measure and cut out a section of contact paper that is double the size of one side of the paper sheet. Remove the backing from the contact paper and slowly cover one side of the paper sheet. Smooth out any bubbles or wrinkles that form. Then enfold the other side of the paper, to cover the divider completely. Cut away excess edges. The resulting divider sheet is now strengthened. Find a piece of cardboard that is strong and thin. Art quality cardboard or cardstock is ideal (even ripped old dividers can be repurposed for this). Avoid using anything that is too thick or it will add bulk to the folder. Align the cardboard with the notebook paper and cut to size if needed. Glue the cardboard to the notebook paper; if using ripped old dividers, tape the ripped section flat before gluing onto the notebook paper. Allow to dry before proceeding and make the remaining dividers as well. You now have a set of strengthened divider sheets.
Measure a small rectangle on white cardstock. The rectangle should be around the same size as a tab would normally be, although you’re free to adjust the size as needed. Cut out the rectangle. Write the name for the relevant divider onto the tab. Cover the tab in contact paper. Glue the tab to the divider (paper glue or spray adhesive work well). Alternatively, leave an edge of contact paper on one side when covering the tab, and use this to attach the tab to the divider sheet. Continue in the same way with all of the remaining divider tabs.
