Take a piece of wood
Draw a shape on the board using pencil. I did a heart but whatever is fine.
Place nails along the pencil line.
Nail the nails to the board.
Now using string lace the nails in no particular fashion.
Add as much string as you want
Do layers of different colors for the best effect.
And you're done.
Enjoy. Like and follow. :) comment any guides you want me to do.
