You can make an unusual and stylish piggy bank with your own hands from an ordinary tin can with a lid for storing bulk products. For this, special knowledge or skills are completely unnecessary, the main thing is that your hands are at least somewhat skillful. We will decorate a tin can with strips of paper towels, creating a relief of randomly laid fabric, followed by painting with acrylic paints, decorating with mother-of-pearl semi-beads, decorative chains and small golden locks.
To make a piggy bank from a tin can we will need:
- tin can of any size and shape
- roll of paper towels
- PVA glue about 200 gr.
- acrylic paints black matte
- acrylic paints gold
- semi beads
- decorative chain
- small locks
- coins of different denominations
- glue Titan
- hard and soft wide brushes
- black beads (a little)
First you need to cut strips of paper towels about 4-5 cm wide. Dilute PVA glue with water 1:1 in a container with a wide neck. It is more convenient to “work” with a rectangular or square tin can; in the process you will understand “why”.
How to make a piggy bank with your own hands from a tin can
Dip the prepared paper towel strips one by one into the diluted glue. When removing the workpiece, you need to squeeze it slightly, passing it between two fingers. You should act carefully, without pressure, to avoid tearing the paper. The strip should only be saturated with the adhesive mass, but not soften in it. The resulting strip must be carefully placed diagonally on the tin, creating random folds, like on fabric. Thus, it is necessary to lay the strips on one side of the jar and leave the craft until the glue dries. The opposite side is covered in a similar way. In total, you need to make two or three layers of paper towels to make the piggy bank look solid and stylish.
This is what the workpiece should look like:
A completely dried piece can be decorated. First you need to paint it in the base color, for which we take matte black.
Before painting, acrylic paint must be diluted with water in the proportion of 1 part paint: 2 parts water. It is recommended to use a wide soft brush. While painting, try not to miss any folds and fill every millimeter of the future piggy bank with paint.
Now the paint should dry completely. It will take about 5 hours. In the meantime, you can start decorating the lid of the piggy bank.
Decoration of the piggy bank lid with coins, semi-beads and seed beads
First of all, you need to make a bill and coin receiver from the lid. To do this, simply cut a rectangular hole with a knife. To equip the piggy bank with locks, we cut out a round hole on the sides of the lid and on the piggy bank itself.
Now let's glue the coins using Titan glue. We apply glue to the coins and place them on the surface of the lid in a random order, in a slightly disorderly manner. We decorate the hole for the money with beads, gluing them in the same way as coins. We “fill” the gaps between the coins with black beads.
The penultimate stage of making a piggy bank with your own hands from a tin can is applying gold acrylic paint. To do this you will need a hard wide brush.
There is no need to dilute the gold paint!
The gold decor is applied to the surface of the folds of the piggy bank's trim with light brush strokes, lightly touched with paint. When dry, the gold decor on a black background creates the effect of old red gold, glitters beautifully in artificial light, and looks expensive!
If you take a small piggy bank with your own hands
not only as a children's toy, not only as some kind of temporary means of saving, but as a reason to make an interesting decorative element for the interior, then the task changes a little. Now it is not enough to cut a hole in the box for coins and bills, you also need to decorate this box with dignity, no worse than. It is about interesting ideas for organizing a home bank that we will talk below.
Textile decor
Required materials and tools:
- glass jar with lid;
- fabric and ribbons for decoration;
- glue gun;
- scissors and a sharp knife.
Step 1. Cover the jar with cloth; use a gun for this.
You should not choose very thin or light-colored material as finishing, as glue may be visible on it.
Step 2. Using a knife, make a rectangular hole in the lid for coins. Then cover the lid with the same fabric as the jar. Make a cut in the center of the jar and carefully wrap the material inside, securing the edges with glue.
Step 3. Glue decorative tape along the edges of the lid.
That's it, your piggy bank is ready! You can add details to your liking - rhinestones, sequins, beads. Or place a photo on the accessory, so you will combine two decorative items in one - a piggy bank and a frame.

OPERATING INSTRUCTIONS
Before starting work, you need to calibrate it for your coin, this is done as follows. The Arduino has a reset button, and next to it there is our calibration button. We press the calibration button, and then reboot the Arduino, without releasing the button. The service button will appear on the display; hold the button for 3 seconds. Then the message memory cleared will appear. This procedure resets the number of coins that were thrown into the piggy bank. Let go, the calibration process starts. Now you need to throw coins into the piggy bank with the price indicated on the display. The system finds the maximum signal value from the sensor for each coin and writes it into memory; all settings are saved even after a reboot. That's it, the piggy bank returns to normal mode.
Let's count how much change I had in my wallet. Now the system is in deep sleep and has eerie digital dreams. As soon as I insert a coin, the contacts at the entrance to the slot close, and the Arduino wakes up and turns on the display and sensor, and begins to wait for the coin. If you stop throwing coins, the display will go dark and the Arduino will fall asleep again. And now I’ll show you another interesting function: insert a coin and hold it for a few seconds, that is, we close the contacts. And the display shows the price of the coin in the first line, and the number of these coins in the second line, that is, we know how many coins of each type are in the piggy bank at the moment. And then we fall asleep again.

Step 1. Before you begin, the jar needs to be prepared. If necessary, remove the label, get rid of traces of glue, and degrease with alcohol.
Step 2. Carefully make a hole in the lid for coins.
Step 3. Dip a sponge into acrylic paint and, using gentle movements, apply it evenly to the surface of the lid and jar. The coating should be as thin as possible. After this, let the future piggy bank dry completely and apply paint in two more layers.
Step 4. Carefully tear off the part with the design you like from the napkin. In this case, you should not resort to scissors, since the torn edge will be less likely to be replaced on the finished product. Then very carefully peel off the top layer of the napkin where the design is applied. It is important to choose an image that is proportional to your jar. Please note that after subsequent manipulations the napkin will increase in size.
Step 5. Dilute PVA glue with water in a 1:1 ratio. Place the napkin face down on the file. Spray thoroughly with water using a spray bottle and apply diluted PVA.
Step 6. This is the most important step in creating a piggy bank. Carefully attach the file with a napkin to the outside of the jar, pressing lightly with your fingers. Then carefully delete the file.
Step 7. Using a dry brush, go over the surface of the napkin. Perform this manipulation from the center to the edges. Gently smooth out any wrinkles or air bubbles.
Step 8: Leave the jar to dry completely. Any remaining imperfections (bumps or creases) can be carefully rubbed out using soft sandpaper.
Step 9. To fix the picture, you need to cover the jar with acrylic varnish. It is better to do this in 2-3 layers. It’s just important to let the jar dry after applying each one.
Advice! To prevent coins from damaging the bottom of the jar, place foam rubber or several layers of soft cloth.

Any container where you can put coins or paper bills is suitable for a piggy bank. The money vault should not be opened so that part of the savings cannot be taken out from there. You can buy it in a store or make it yourself, and the cost of creating it can be minimal. Before making a craft, you need to solve the questions: what materials will it be made from and how to make a piggy bank with your own hands.
