I had what I thought was a nicely completed logo for my friend's company. But on closer examination, a hand-drawn "swish" over the main text, has serious imperfections! I copied the swish to another layer and began experimenting with it. I managed to cover some extraneous markings near the swish, by placing white shapes over the markings. They're covered up now. But when I tried to fill in some "cracks" in the actual swish, by placing shapes of the same color over the cracks, it didn't work. The blue shapes over the blue swish looked darker. There's a field in the Layers dialogue box that says "Normal." I tried the other options and none of them worked. Is there a way I could cover the cracks in the light blue swish with the exact same color as if this were a raster image in GIMP or something?

I also tried doing a screen-dump and putting the swish in Paint.Net, a raster program. But that means the swish will lose its vector properties!

Any help with this will be very much appreciated.

Could you please try to make your answers as literal and simple as you can? I'm severely dyslexic and have very poor eyesight, and I'm an Aspergers person among other yucky stuff.
