I am a former Filofax user and learned about the Midori / traveler's journals recently. I wanted to find a way to make use of my Filofax so I transformed my personal size filofax into a traveler's journal by removing the rings / metal spine with a hacksaw. For illustration purposes, I found the green binder picture online, (it's not mine) and I bent the metal spine up like the picture shows, but not quite as far. I bent it up just enough to get a hacksaw blade between the leather and the rivets and I literally sawed through the rivets on the inside of the book. After removing the rings and metal spine, I used a leather hole punch to make 3 holes to each the top and bottom of the leather spine, giving me 4 elastic strands inside. It holds inserts I modified from May Designs and these inserts measure 7.25 x 5 inches. I used a rotary cutter to trim from the bottom and top of the notebooks, then reinforced the stitching of the books so they wouldn't come unsewn. I angled the corners of the notebooks to fit inside the curved corners of the Filofax. I am really happy with it and am loving that I can still use the Filofax to satisfy my TJ obsession! Thanks for looking!
