Thanks allot
that helped I made the text first and got the perfect size and length then I mad another elipse white and adjusted the thinkness of the color white and size of of the elipse
to match the text so the text was centered.
then I used the eraser tool and adjusted the rotation on that to cut off the right amount edges and erase the rest of the white elipse so it made the rocker banner.
and were Im using it for a stincile I reversed the color from white to black and the text transparent.
