Watermelon season in full swing, it is the perfect time to make some juicy bright red crafts and enjoy a popsicle with a book!
This watermelon corner bookmark is simple to make for teens and adults, and can be a good practice of cuttin and gluing for younger kids. You only need a printable template (you can get below), glue stick, and scissors.

I used thicker print paper and the bookmarks sit perfectly on the corners, but as printing paper is still thinner that cardstock, these corner bookmarks will sit tighter if you put them over a few pages. There is actually two ways of setting this bookmark on the page, too, I will show you!
Supplies You Need
- Color printer (you can print them black and white as alternative, but colored parts will be grey and you will need to use markers, not crayons or pencils, to cover it up)
- Thick paper so bookmarks holds up better over time.
- Scissors (Child-safe scissors for younger kids)
- Glue stick
If you want to extend the lifespan of the bookmarks, run a strip of clear tape along the inside pocket seam after gluing. Optional, but it makes them noticeably more durable, especially for younger children who aren’t always as gentle with their books as we may hope for.
Total time to make this is under an hour for any age, but older kids and adults will be done within 20-30 minutes tops.

How to Make Watermelon Corner Bookmarks
Step 1: Print
Download the PDF, open it, and print on standard letter or A4 size paper.

Step 2: Cut Along the Outer Solid Line
Each template has a solid black outline, this is out guideline to cut it out.

Watermelon shape in this case is suuuper simple even for younger kids, as there are no details, tails, wings, or anything like that.
It is a good practice to remember to turn paper following the line rather than the working (cutting) hand with scissors.
Step 3: Cut Down the Center White Solid Line

You will see that the template has dotted lines in the watermelon “body” and one thicker white solid line running down the middle from the corner of the rectangle.
You will need to cut this out as clean as possible.
Step 4: Folding
Watermelon has three dotted fold lines running from the center. Lay it in front of you like this (eyes up):

Fold one at a time, strictly! First fold the bottom part to the back. You can flip the craft and you will see this on the back:

Next, fold the white part of the left onto the juicy slice part:

Fold the remaining red triangle to the back, again. When you flid the bookmark again, you will see the word glue staring at you:

Step 5: Glue The Bookmark
So do exactly that, apply glue onto the red triangle and gently press the last flap onto it. Make sure it is glued together well.

And your summertime watermelon bookmark is done!
Now, there is two ways this watermelon slice can sit on a page: with full body on the front of the page or only the top (face):


This little pocket of a bookmark is too cute, honestly!

What Age Is Watermelon Bookmark Craft Good For?
I think that my watermelon bookmark works well for ages 6 and up with adult help, and kids 10 and older can do it on their own without any issues.
At the same time, the shape is REALLY easy, so you can do it even with kids under 6 years old, if you cut and help them fold and glue. Younger kids may not be as interested in properly sitting down to read, but they can use this watermelon for any playtime.
Meawhile, this craft may not look like much but it builds scissor control, following fold directions in sequence, and spatial reasoning as they figure out which flap goes where. It is nowhere near origami level of complexity, but trust me even I was able to fold and glue it two different ways and one was, well, wrong haha.

A few tips
The center cut is the trickiest step, and if kids cut the dotted fold line instead of the solid white line, the whole thing falls apart. So please keep an eye on the step number 3.
Photo paper or card stock from a home printer works well, too.
If you don’t want to glue it, you could technically use a stapler but only to staple the two back flaps, not all the layers! Or it won’t slide onto the page at all.
