words bleed outside shape

I used a custom shape, and it's barely visible. The words continue to repeat outside the shape, just in a slightly fainter color. How do I have a hard edge to my shape, and nothing in the background?

Hi Maria,

this is because when you uploaded your shape the threshold value was set near 1 that forces Tagul to include white background as a part of your image. Thus words are placed on white background as well.

You need to upload your image again and make sure you moved threshold to somewhere about 0.8 to make sure the white background is removed.
