You will need all of the following you see in the picture. I forgot to put tape in the picture haha, you'll be needing that :)

next, take some music paper, you can make your own.. and draw some random music notes!

Take the cover of a magazine, draw a heart and cut it out. This will be your tracing heart you'll be needing later...

Now on your music sheet, trace 21 hearts.

And cut them out...

Now do the same exact thing with magazine paper. You will also need to cut out 21 hearts.

Here they are!! :)

now take two pages from a magazine, and something equivalent to a chopstick.

Roll the pages up!

And tape it in place. remove the chopstick.

Do the same thing to the second page.

Now take thread and tape it to either a magazine heart or a music heart.

You'll also have the thread taped to the rolled up magazine page.

Then, with the thread taped on one heart, attach the other heart. you should have a two sided heart. One of the music, and one of the magazine.

It will look like this :)

I taped it to a piano stool to show the layout.
You should have two short strings on the ends with two hearts.
Then the string next to it will be slightly longer, having three hearts.
Finally, the middle string with be the longest and also have three hearts.

Connect the two rolled up pages of magazines in a criss cross fashion and on the second one, you should have two strings on each side. Having two hearts on each. Again the outer strings will be shortest.

So there should be five strings on one magazine stick and four on the other. attach a string on the top and hang it up.
I hope this wasn't too difficult to understand. But it's really cute, and I hope you enjoy. :)
