If you've been looking for a way to organize ephemera, documents, photos, stickers, or receipts — and you want something that looks handmade in the best possible way — this tutorial shows you how to make envelope books two ways, using materials you likely already have. The accordion-fold construction is simpler than it looks, but there are a handful of things that will make or break the result, and I walk through all of them here.
What we cover
This tutorial covers building a chipboard-cover envelope book with an accordion-fold spine, from choosing and preparing your paper through covering and finishing the boards. You'll see two structural variations — one where the book opens completely flat, and one where ribbons hold the envelopes contained in book form — plus a flip-through of three finished examples made with different envelope types, cover materials, and uses.
What you'll learn
How to choose the right paper for your accordion spine — this is the detail that trips people up most. Copy paper (around 80gsm) is too thin and floppy; heavy cardstock folds unevenly and pulls your envelopes out of alignment. A medium-weight paper — something in between — gives you the cleanest result. You'll also learn how to identify paper grain and why folding along the grain direction matters for keeping everything square.
How to fold a perfect accordion without a scoring board, including:
- The freehand halving method — fold in half, then fold each half back to the fold line — which gives you six pockets with near-perfect alignment every time
- How to extend the method using a scoring board mountain-by-mountain if you want eight pockets instead of six
- Why scoring all your lines at once then folding produces misaligned folds, and why freehand folding is more reliable despite feeling less precise
Why you leave a 2-inch tail at the start of the accordion — that free strip is what gets glued to the back cover board. Starting your folds right at the edge leaves you nothing to work with.
How to glue envelopes into the accordion pockets cleanly, including:
- Using double-sided tape on each mountain peak first, then applying glue on top — the tape holds, the glue gives you a few seconds to slide the envelope into alignment before it sets
- Why the first envelope is the most important to get right — everything else references it
- How to check alignment at top and bottom before pressing down
How to cut and cover chipboard cover boards, including:
- Sizing panels slightly larger than your envelopes
- Covering with scrapbook paper, newspaper pages, fabric, or book pages — any of these work
- Mitering corners cleanly using the fold-and-press method, with double-sided tape on the short sides after the long sides are wrapped
How to add a ribbon closure — four short ribbon lengths glued to the spine edge of one panel, then repeated on the other panel with just enough give to close snugly without pulling. If you want the book to open flat instead, you skip this step entirely and go straight to gluing the panels.
How to line the inside covers — gluing a panel of the same paper used on the outside creates a clean, cohesive finish that hides the raw chipboard and ribbon ends.
How to label and decorate the front cover without stamping directly onto your sticker or decorative element — stamp onto card stock first, trim, then glue it down. This lets you fix mistakes before anything is committed.
Three variations shown in the finished flip-through:
- Side-opening craft envelopes with a bookplate and six pockets, kept contained with ribbon
- Decorated craft envelopes with scrapbook paper added to the flaps, in an open-flat construction
- Large manila envelopes with added back pockets on each envelope, covered with upholstered fabric instead of paper — showing that when your envelopes are larger than 12×12, fabric is a practical alternative to paper
Tips & gotchas
Paper weight really does matter. If it's too thin, the spine will be floppy and the envelopes won't sit flat. If it's too heavy, your folds will wander and the finished book will look uneven. Middle-weight paper — think a decent sketching or text-weight paper — is the sweet spot.
Check your paper grain before cutting. Fold a corner gently in both directions; one direction will feel noticeably smoother. Cut your accordion strip so the grain runs the same direction as your folds. It makes a real difference to how crisp the folds land.
Six to eight envelopes is the practical range. The freehand halving method naturally gives you six pockets. Getting to eight is possible with the mountain-by-mountain scoring approach, but precision matters more with each additional fold. Beyond eight, join two strips of paper rather than trying to fold a single long strip.
Don't rely on double-sided tape alone. For attaching envelopes to the accordion and for cover construction, double-sided tape is useful for positioning — it gives you a moment to shift things before the glue sets — but on its own it loses grip over time. Always layer glue on top.
Apply glue over the double-sided tape when attaching envelopes. Sounds counterintuitive, but it gives you a window to move the envelope into perfect alignment. Press straight down onto double-sided tape alone and you'll have no chance to adjust.
Don't apply so much glue that it seeps from the edges. This is especially important when gluing accordion panels to the cover boards — excess glue creates lumps under the cover paper and can stick things together that shouldn't be stuck.
If you want the book to open flat, skip the ribbon entirely. The ribbon step is only for the contained, book-form version. If you go back and add ribbon after you've already glued the panels, you'll have a much harder time getting the tension right.
When stamping a label, stamp on card stock first. If a letter stamps too large, too close to its neighbor, or just slightly off, you can start over without ruining your sticker or decorative element. Get it right on card stock, trim, then glue it down.
A small version with side-opening envelopes works beautifully as an ephemera holder for a junk journal in progress — everything sorted, nothing loose. A large manila-envelope version covered in fabric becomes the kind of document organizer you'd actually use for birth certificates and insurance papers. The open-flat version is particularly good for photos or flat artwork, where you want to be able to see everything at once rather than paging through. The same structure scales up or down, and once you've folded a clean accordion you'll find yourself thinking of more uses for it than you have envelopes for — which is a good kind of problem to have.
