How to make seamless texture?

I’m making raindrop effect using tutorial.

[->tutorial link][1]

I made until 9:25 of video.

after 9:25 , I couldn’t understand. so just change texCoord 1,1 to 4,4 and assigned plane

but i can see that lines of repeated textures

video has no lines.

how can i fix this?

answer is at this link
