Back-to-school shopping season is in full swing, and somewhere between the pencil pouches and the mandatory glue stick multipack, there’s always room for one thing that costs almost nothing and gets used every single day: a bookmark that doesn’t slide out of the book the second you close it. Corner bookmarks solve that problem because they slip over the page like a little pocket. Turn them into googly-eyed monsters and suddenly a kid who \”forgot\” their bookmark at home stops forgetting.
This is a felt project you can finish in under an hour, using scraps you probably already have. No sewing machine required, though a needle and thread (or fabric glue if you’re impatient) will get the job done either way.
What You’ll Need
- Felt squares in two or three colors (a multipack of stiff craft felt works better here than the thin fabric-store stuff)
- Small buttons or googly eyes
- Embroidery floss and a needle, or fabric glue
- Fabric scissors, plus pinking shears if you have them
- A ruler and fabric marking pen or chalk
Step One: Cut Your Squares
Cut two squares of felt, roughly three inches by three inches, in whatever color you want the monster’s face to be. Stiff felt holds its shape better than the soft stuff, which matters once this thing is getting shoved in and out of a backpack for a semester.
Step Two: Fold and Fit
Fold each square diagonally to form a triangle, then check the fold against the corner of an actual book page you plan to use it on. You want it snug enough to grip the page but not so tight it tears the paper. Adjust the size now, before any stitching happens, because unpicking felt seams is nobody’s idea of a good afternoon.
Step Three: Stitch the Pocket
Line up the two triangles and stitch along the two short diagonal edges, leaving the long folded edge open so it can slide over the page corner. A simple running stitch or whip stitch is plenty; this isn’t a garment, it doesn’t need to survive a washing machine. If hand-sewing sounds like a chore, fabric glue holds up fine for something that only gets gentle daily handling.
Step Four: Give It a Face
This is the part kids actually care about. Sew or glue on button eyes, snip a jagged mouth from white or contrasting felt for teeth, and add felt horns, antennae, or ears cut from scraps. Asymmetrical is better than perfect here \u2014 a monster with one eye bigger than the other has more personality than one that looks store-bought. If you’re using real buttons instead of googly eyes, go with something flat-backed so it doesn’t dig into little hands.
Step Five: Trim and Finish
Once the face is attached, trim any stray threads and round off the two front corners with scissors if you want a softer look. Pinking shears on the open edge add a nice zigzag detail and help disguise any less-than-perfect stitching, which, no judgment, happens to everyone on their first felt project.
Why Corner Bookmarks Actually Work
Flat bookmarks fall out. Everyone knows this. A corner-style bookmark stays clipped onto the page no matter how the book gets tossed into a bag, which is honestly the whole point of a bookmark in the first place. If you want to go deeper into the folding technique with paper before committing felt to it, there’s a good breakdown of the corner-fold logic over on Instructables that’s worth a look before you cut your good felt.
Make a batch of five or six in one sitting \u2014 different colors, different monster personalities \u2014 and you’ve got teacher gifts, party favors, or just a stash so there’s always a spare when one inevitably goes missing in the couch cushions. A small tin of assorted craft buttons makes it easy to give each monster its own weird little face without buying anything new for every batch.
