How to Make a Cardboard Harp – String instrument

This Cardboard String Instrument makes music just as a store-brought toy would.

A String Instrument toy was on my crafting wishlist for a long time. My little one has all other musical toys like a keyboard, flute mouth organ, and drum.

Among all the String instruments, Harp caught my attention. It has a simple yet most beautiful and eye-catching appearance. So decided to give it a try, and so here is my Harp-inspired cardboard Toy.

Directions to make a Cardboard Harp

Mark Footprint and Cut Cardboard

Download the template and cut the Harp out.

Place the Cutout Harp template on a sheet of cardboard and mark the outline with a pencil. Cut the cardboard out using a cutter. Make ‘n’ number of pieces as required.

How do you know how many you need? Consider two things; The thickness of the Cardboard and the Length of the screw. For instance, I made 5 pieces of cardboard (combined thickness is 20mm), whereas the depth of my screw is 32mm.

Next, mark the Screw position on a cardboard cutout.

(Punching holes in the template will be helpful to mark the position of the screw on the cardboard)

Combine the Cardboard cutouts

Glue the cutouts one above the other with white glue. Make sure that they are all well-aligned. Also, make sure that the cardboard cutout, marked for the screw position, is on the top.

You can place a weight over them and let them dry for 10 to 20 minutes. Once it is dry, check for undulations on all sides. If there are any, use sandpaper or a cutter to scratch them out.

Insert the Screws

Insert the screws one by one in the marked positions using a hammer. I preferred screw-over nails because they cannot be pushed in or pulled off by my kid.

As my nail is 32 mm, 12mm was projecting on the top after inserting 20mm into the cardboard base. This projection can be used to hold the strings.

On the rear side of the cardboard, some nails might protrude a little. If it happens, cut another thick piece of paper or cardboard and add a layer at the rear side.

Add the Strings

Finally, add the main element of the project – the strings/rubber bands. Add the right size rubber bands such that the strings are in full tension. The tighter, the better.

You can also paint with acrylic paint and add small intricate patterns with a fine-tip pen.

Tada! It’s ready!

We totally loved the output, and my child loved making music with it. It was also convenient for her to take along.
