I cut strips of craft paper 3 x 5 and scored at 1", 1 1/2", and 2".
Fold in half and create holes with your Bind-it-All, or similar device. Secure the outer part where the holes are, being careful not to get glue in the holes. I ran a thin line of tape with my 1/4" ATG gun, but you could also use a red line tape in 1/4". A glue stick would also work fine as long as you're neat about it and keep the glue out of the holes. Do not glue the outer portion, you will spread this open and attach to the tags, or whatever you are using as pages.
Now you will spread apart the outer portion and apply glue. I recommend a soft type of glue stick so you can wiggle it around and line it up as shown below. I used a scotch craft stick.
Make a mark on your tags where you will be placing your tabs so they will all be even. Slip the tag in between the tabs and wiggle around until it's even and secure.
The journal contains many flip open pages. They were assembled before any patterned paper was added as shown.
