I would use a for loop to make different y positions for your lines.

The x positions will need to differ by a random amount.

You can draw lines with the `line()` function.

You can generate random numbers with the `random()` function.

It is hard to help you more without seeing your code.

Please post your current code for more help.

For more help, post your current code.

You should post your code. Then we can help you more.

Notice that I’ve said you should post your code three times.  
That’s because it’s important. You should post it.

for (int y=0;y\<=height;y=y+6){  
line((int)random(45),y,(int)random(45),y);  
}  
for (int x=0;x\<=width;x=x+12){  
line(x,(int)random(45),x,(int)random(45));

Parallel != vertical != horizontal
