Good morning and cordial greetings to everyone this morning I want to show you how you can make a four with useful material.

My materials were
Cardboard, scissors, paint, thread, foamy and silicone

Step 1
Paint the shape of a four on the cardboard and cut out

Step 2
Cut 2 long strips. Since I used a cardboard with a layer of silk on top I removed that layer. And stick all around our four

Step 3
Once completed in second step. Then we paint everything.

Step 4
We cut the foamy in the shape of a tie and stick in what is the middle of our four covering the entire thin part

Step 5
In cardboard we cut out a small box, we lined it with foamy and we took out some small teeth to be able to put our rope

Step 6
Take out 4 small sticks and the same amount of small foamy circles. First stick the sticks on the guitar and on this the foamy circles

Step 8
We cut a circle and glue in the center

Step 9
With a thread or nylon we make the rope. First roll up and finish down. So you will do with all

And if we finish our four. Thanks for reading God bless you

Nice one from you... To be able to achieve this, someone needs to have a full detail and also be very creative.
You are doing well.
Buena idea. Suerte.
