Practical craft ideas made with everyday materials (1–10)
A chair made out of cardboard

In recent years, cardboard has been gaining attention as a material that can be used for disaster-relief beds, toilets, partitions, and more.
Cardboard is lightweight, and depending on how it’s assembled, its strength can be increased.
Because cardboard is also a familiar material for crafts, consider using it for summer break independent research or craft projects.
A cardboard chair that can be made simply by assembling pieces cut and notched from cardboard looks cool, is highly functional, and is a project you can actually use after making it.
DIY of small furniture

Let’s make a sturdy wooden storage box that you can also sit on.
Cut the lumber with a saw and assemble the pieces.
These days, many home improvement stores offer lumber cutting services, so it should be easy to give this a try.
By attaching a cushioned pad to the top of the box, you’ll improve seating comfort.
Before you start, create a plan drawing and check the required materials and measurements.
Some steps may be difficult for children, but why not make it together as a family?
Conveyor Piggy Bank

A conveyor-belt coin bank that swallows coins one after another! Make the main body of the bank from a milk carton, and install a mechanism inside using items like bamboo skewers, thick paper, plastic bottle caps, and rubber bands.
Then, combine the mechanism with a belt, and you’ll have a coin bank where turning a lever moves the belt.
Adding a face around the coin intake gives it a comical look.
If the belt’s joint is misaligned, it won’t run smoothly, so be sure to attach it straight when connecting the ends.
kaleidocycle

A kaleidocycle whose patterns spin and change, pleasing to the eye.
Let’s handcraft a kaleidocycle using empty milk cartons! Open up two milk cartons, draw lines and make mountain folds, then form sleeves and fold the edges inward to create the segments.
Do the same on the other side, and simply secure with tape.
You can attach your favorite designs or draw illustrations on it, too! It’s a simple build that will astonish anyone who sees it, so take advantage of the summer break and give it a try.
beetle (specifically, a rhinoceros beetle)

Let’s try making beetles and stag beetles—the classic insects of summer—using a hot glue gun.
If you use the finished pieces as decorations, they’ll really emphasize a summery atmosphere.
Create each part on a sheet of parchment (baking) paper, and then glue the parts together at the end to complete the model.
Giving each piece a good rounded shape is an important point for achieving a three-dimensional look when it’s finished.
You can aim for a realistic appearance, or play with colors and shapes to create your own original creatures—it could be a lot of fun.
