If you have ever lost your place because a flat bookmark slid right out of your bag, a book thong is about to become your favourite little make. In this guide I will walk you through how to crochet a book thong from start to finish — what it actually is, the handful of stitches you need, the yarn and hook to reach for, and how the whole thing comes together — so you can decide to cast one on tonight.
It is a confident-beginner project, it uses less than 40 yards of yarn, and most makers finish one in an evening. By the end of this post you will understand exactly how a book thong is built. When you are ready to sit down and make it stitch by stitch, the full printable pattern is waiting for you at the end.
What Is a Book Thong?
A book thong is a wrap-around crochet bookmark with a clever two-part design. A wide band hugs the closed pages of your book — it sits snugly over the block of paper, so it never falls out and never gets lost at the bottom of your tote. From that band hangs a slim tail, or “thong,” that slips between the pages you are actually reading.
When you close the book, the band keeps everything in place. When you open it, the little tail marks your page. It is the kind of small, useful, pretty object that makes people ask “wait, you made that?” — which is exactly why it works so beautifully as a gift.
Why Learn How to Crochet a Book Thong?
Beyond being genuinely useful, this is one of the most satisfying quick makes in the whole craft. Here is what makes it such a rewarding project:
- Confident-beginner friendly. You only need four basic stitches — no fancy techniques, no shaping headaches.
- A tiny yarn budget. It is a true stash-buster, using scraps you already have. No full skein required.
- A genuinely quick finish. Most makers complete one in one to two hours, and the second one goes faster.
- Endlessly giftable. Pair it with a paperback for birthdays, book club, teacher gifts, hostess gifts, secret santa, or a “just because.”
It is the kind of pattern you make once and then find yourself casting on again before you have even put your hook down.
What You’ll Need to Crochet a Book Thong
One of the best things about this project is how little it asks of you. Here is the short shopping list — and a few tried-and-tested recommendations if you need to top up your supplies.
- Yarn: Worsted-weight (#4) yarn. 100% acrylic is recommended for durability and easy washing. You will need roughly 25–40 yards of a main colour, plus 10–15 yards of a contrast colour if you add the optional border. Reliable workhorses like Red Heart Super Saver, Bernat Premium, or Lion Brand Vanna’s Choice all work beautifully (shop worsted-weight yarn on Amazon).
- Hook: A 4.5 mm (US 7) crochet hook. A comfort-grip hook like the Clover Amour makes those quick evening projects even easier on your hands (see 4.5 mm hooks on Amazon).
- Notions: A yarn needle for weaving in ends, two stitch markers, and a sharp pair of scissors.
Prefer a crisper, more structured bookmark? Cotton works wonderfully here too and gives the band a little more body.
The Four Stitches You’ll Use
This really is a beginner-friendly make. If you can work these four stitches, you have everything the pattern needs:
- Chain (ch) — the foundation you build on.
- Single crochet (sc) — the main stitch that forms the band and body.
- Slip stitch (sl st) — used to join and to finish edges neatly.
- Single crochet decrease (sc2tog) — this is what tapers the body down into the slim tail.

How a Book Thong Comes Together
Here is the big-picture view of how the piece is built — think of it as the map, not the turn-by-turn directions. Seeing the shape first makes the full pattern feel effortless when you sit down with it.
You begin with a long foundation chain that you join into a smooth ring. A couple of rounds of single crochet turn that ring into the wide band — the part that will hug your closed book. From there, you stop working in the round and switch to flat rows, gradually decreasing stitch by stitch so the piece narrows down into a slim two-stitch strap. That strap is the “thong” that slips between your pages.
To finish, you join the end of the strap back to the band to close the loop, then — if you like — add a tidy cleanup round and a pretty scalloped shell-and-chain border. That is the entire journey: ring, band, taper, strap, join, border. Simple, logical, and quietly addictive.
The full pattern walks you through each of those stages slowly, with exact stitch counts and a printable row-by-row table so you never lose your place.
Three Tips for a Clean, Professional Finish
A few small habits make the difference between a bookmark that looks homemade and one that looks handmade:
- Keep your tension even and relaxed. A band that is too tight will cup; too loose and it will not grip the pages. Aim for steady, comfortable stitches.
- Weave in your ends properly. Thread each tail onto your yarn needle and weave it back through several stitches in two directions so it never works loose.
- Give it a gentle press. A light steam block relaxes the fabric, flattens any curl in the band, and makes the border sit crisp and even.
Fun Variations to Try
Once you have made your first one, it is almost impossible to stop — and the pattern is designed for exactly that. Inside the PDF you will find eight built-in variations so every book thong you make feels completely different:
- A Petite Pocket Thong sized for small paperbacks and journals.
- A Hardcover Hugger for textbooks and chunky novels.
- Two-tone colour-block and striped-strap versions.
- A textured back-loop-only band, a tassel-and-charm finish, a cotton-for-crispness swap, and a mini embroidered motif like a heart or an initial.
They are the perfect way to use up every odd ball in your stash and build a little collection — one to keep, the rest to give away.
The Perfect Handmade Gift
A book thong is a gift that lands every single time. It is quick enough to whip up a whole batch, inexpensive enough to make from scraps, and thoughtful enough to feel special. Tie one around a new paperback with a length of kraft twine and you have a present that looks like it came from a boutique. Book club, teachers, the reader in your life who has everything — this is your answer.
