Thank you so much BoltBait for your fast reply. I followed your detailed instructions and downloaded and installed the new tools. They are shown in "Effects". However, I am having a little problem getting them (feathering) to work for me. I opened a photo that I had recently cut out, which I saved as a JPEG. The photo has a white background. I then used the selection tool and selected the photo itself, then control I to invert the selection. At this point, I opened your feathering tool and tried numerous ways to make it work for me with no result.
Am I doing something wrong here? If you will be kind enough to help me figure all this out, I will be pleased to ante up a small token of my appreciation for your efforts. Many thanks.
