Trying to draw a feathered rectangle

[JoeButi]

I have a jpg in Elements. How can I draw a rectangle in the image, color it white and feather the edges? I have tried everything and am not sure it can be done. Sounds odd but it's to design a book cover. Thank you for any suggestions.

Here is  another way to do it:

• Open your jpeg
• Create a new layer
• Select the rectangular marquee tool
• In the tool options, choose a feather amount

• With your new layer selected, draw your rectangle
• [Optional] In the Marquee tool's options, click on the Refine Edge button.  This will open another dialog where you can adjust the feather amount:

• Select the Paint Bucket tool
• In the Tool Options, make sure that the All Layers box is unchecked:

• Press X once or twice to make the foreground color white
• Click on the feathered regtangular selection to fill it with the foreground color:
