page corner bookmarks

This project comes to you at the request of Twitterer @GCcapitalM.

I used to believe that a person could never have too many books, or too many bookmarks. Then I moved into an apartment slightly larger than some people’s closets (and much smaller than many people’s garages) and all these beliefs got turned on their naïeve little heads.

But what a person can always look for more of is really cool unique bookmarks. Placeholders special enough for the books that are special enough to remain in your culled-out-of-spacial-necessity collection.

Page corner bookmarks are cute, practical and deeply under-represented in the world.* They’re easy to make, easy to customize, and will set you apart from all those same-same flat rectangular bookmarks. Corner bookmarks are where it’s at.

If you like this tutorial, here are a couple others that might be up your alley. First, try making paper plants as lovely, lasting handmade gifts. You can even stash some goodies or small presents in their pots.

If you’re loving the toothy monster vibe, check out these simple monster heating bags, filled with rice or wheat and entirely microwavable, to keep toes or fingers or tummies warm during the chilly winter months. If you want a monster you can wear, try making a cozy bug-eyed fleece monster hat or some fingerless fleece monster gloves.

For the monster-loving adults in the room, try some googly-eyed paper monster wine charms.


*This is probably no longer true, given the astonishing number of you who’ve found your way to this post and made your own page corner bookmarks. Go you! I’m fairly certain that something this adorable and functional can’t be over represented in the world, though, so just keep right on making them.


What you’ll need:

  • pretty paper of cardstock weight OR a combination of plain cardstock and pretty, decorated lighter weight paper
  • scissors
  • ruler
  • mechanical pencil
  • glue stick
  • [optional] other decorating tools, such as crayons, markers, stamps, stickers, ink pads, embossing powder, etc.
  • page corner monster bookmark template  number 3. under “Paper patterns and templates” (or you can make your own using the instructions below)


Putting it all together:

Below, I’ll teach you how to make two similar-but-different types of corner bookmarks. The first is a square overlapped by a triangle , the second is a triangle overlapped by a smaller triangle.

If you are making your own template from scratch, follow all the steps below. If you’re using the PDF template linked to above, cut the pieces out and skip to step 5.

1) Ok, the very simplest thing to do is to cut a triangular piece off the corner of an envelope, and use that. Decorate it if you wish. If you want to get a bit more in depth, ignore the envelope method and move on to step 2.

2) On a piece of plain scrap paper, draw a square. Use your ruler so its sides are perfectly straight. Don’t make it too big – mine measured 2.5 inches x 2.5 inches, though you could go larger than that. Draw second square exactly the same size on the right side of the first square (so they share a side) and a third square exactly the same size on the top of the first square. You should end up with 3 squares that compose an L shape.

3) Using your ruler, draw a diagonal line across the uppermost square, from its top right corner to its bottom left corner. Scribble out the upper left half (now a triangle) of the square, as you won’t be using that part.

Next, draw a diagonal line across the bottom right square, from its top right corner to its bottom left corner. Scribble out the lower right half (now a triangle) of this square.

4) Cut out all parts of the entire shape that have not been scribbled out. This should be a square with two triangles attached to it, one on the top and one on the right. This is your template.

5) Trace your template onto your pretty piece of cardstock (or onto the plain piece of cardstock that you intend to decorate), and cut the shape out.

6) Using your ruler and the tip of your mechanical pencil with no lead showing, score a line (make an indent) along the edges of the square that connect to the two triangles.

  • 6.5) [optional] Cut a square of pretty paper slightly smaller than the one you used for your template and glue it onto the square portion of your shape. I generally do this if the paper I’m using is quite plain.

7) Fold one triangle inwards, so it covers the upper half of the square.

8) Apply glue to the underside (the side still facing up) of the second triangle, and fold it over onto the first triangle.

  • 8.5) [optional] As in step 6.5, if you’ve used plain cardstock and want to glue fancy paper on top of it, cut out a triangle of the fancy paper that’s slightly smaller than the folded-over triangles of the bookmark. Glue the smaller triangle on top of the larger, folded-over ones.

9) Add any decorations or illustrations you wish. Use by slipping over the corner of the page you wish to mark, like a pocket.


Now, here’s how to make a triangular bookmark, where the back is a triangle and not a square.

1) Follow steps 2 and 3 from above.

2) Use your ruler to draw a diagonal line across the remaining, center square, from its bottom right to its top left. Then draw another line, parallel to the one you just created but about 1/2 inch lower down. Erase the first line.

3) Extend the shape’s bottom line and the two side lines so that they meet up. You should now have a shape that looks like a castle flag: a rectangle with a triangular indent at one end.

4) Cut the shape out.

5) Trace the template onto your nice paper. Be sure to make a little mark on either side where the corners of the two outer triangles meet the inner triangle , and extend this mark onto the inside of your shape.

Cut the shape out. If you want a fancy bottom edge, cut that line with fancy scrapbooking scissors.

6) Now follow steps 7 – 11 from above, scoring along the appropriate lines, folding the two outer triangles in on top of each other, gluing them down and adding any fancy paper or other embellishments.

(I actually turned mine over at this point and folded it the other way, so the colours were switched. See below.)


EDIT: Here’s another take on monstrous page corner bookmarks, from another artist who thought it up completely separate from me, long before I even thought of thinking about doing this project or writing this post. Great minds, eh?

2nd EDIT: Many people have seen this blog post over the past months, and many have commented very kindly on it, and many have used the tutorial to make their own page corner bookmarks. A number of the links following the comments below lead to wonderful images of other people’s creative takes on this project. I wanted to post one image in particular here, which I take from the Priestthorpe Primary School Blog. There, a whole classroom of kids made their own page corner bookmarks, and they look fabulous! I love all the different personalities displayed.

Thanks to all of you who’ve shared your own page corner bookmark results, and all of you who’ve said such kind things about the project. It’s heartwarming to think about all the books around the world that are having their page corners nibbled at this very instant.

3rd EDIT: Yet more thanks to all the folks who continue to make use of this tutorial and post your own wonderful versions. Here’s another idea: This crafter decided to use small round stick-on jewels for the pupils, which I think looks great. The downside of course is that they protrude a bit, so your book won’t close flat, but if they’re fairly small jewels it shouldn’t be too bad. Stickers, sequins or paper buttons could also make great pupil substitutes.

    They’re so cute! I tried making them and it was so easy. XD I received lots of compliments from my friends. :)

    Thanks a lot! Thumbs up. ;)

  31. Wow that was strange. I just wrote an very long comment but after I clicked submit my comment didn’t appear.

    Grrrr… well I’m not writing all that over again.
    Anyways, just wanted to say excellent blog!

  32. Hi Tally! I bookmarked your site a long time ago (did I just make a lame pun?). I’ve been admiring this project, but haven’t gotten it together enough to do this with my library classes. I don’t have a lot of time with them. So…I ended up redesigning your pattern just a little bit and adding kid-friendly step-by-step instructions. Want to see? Check out my blog. Thanks for the inspiration!!! I linked back to you, of course. http://www.booksandmarks.com/new-blog/2013/10/23/diy-corner-bookmark-meet-toothy

  35. Hi there, i read your blog occasionally and i own a similar one and i was just wondering if you get a lot of spam
    responses? If so how do you protect against it, any plugin or anything you can suggest?
    I get so much lately it’s driving me crazy so any help is very much appreciated.

  36. It’s nearly impossible to find experienced people about this
    topic, but you seem like you know what you’re talking about!

  37. I comment each time I appreciate a post on a website or I have something
    to add to the discussion. It’s caused by the fire communicated in the article I looked
    at. And after this post page corner bookmarks | Tally’s Treasury.
    I was actually excited enough to post a commenta response :
    -) I actually do have a couple of questions for you if
    it’s allright. Could it be just me or do a few of these
    responses look like written by brain dead folks? :-P And, if you are posting at
    additional online social sites, I would like to keep up with you.
    Could you list the complete urls of all your shared pages like your linkedin profile,
    Facebook page or twitter feed?
