With some time and effort, you will get the results as shown below
It took me around 1-2 hours to do this
Step 1: Gathering the materials
-Glue(Any office/home glue would do)
-A piece of junk cloth
Step 2: Choosing Your Design
After that, print your design out in A4 paper
Step 3: Cut out your design
Step 4: Trace out your art
After that, carefully cut out your design with a pair of scissors or blade
Step 5: Finishing up the design
Use your permanent marker to trace around the art and colour it again to fill up any blanks.
Step 6: Stick it onto your guitar
Turn your design around so that the white surface is facing up. Take your glue and dab around the surface and carefully place it on your guitar.
Take a wet cloth, and wipe around your design to lose the glue stains.
