help with the 'fill' option

Yes, much of this helps and will guide me as I try again to create a spiral image.  I tried to follow a tutorial on the Photoshop Taining Channel.  I started with a photo of a single duck.  I then did a select subjecr---and tried very hard to trim down the edges so that my selection would not include very much of the water.  I have taken a basic Photoshop class and we did not gt into working with 'fills'.  I think that when I created a new layer it was a layer with all the checks---not a solid white.  I defined the duck as the pattern and he appeared as does your rubber duck image----on a checkered background.  I then went to try out sone of the different scripts and happened upon 'spiral'.  I would love to get a final image which would show the ducks spiraled around a central point and then be able to print this spiral image onto a greeting/note card---size 5 X 7".  I will try to adjust the scale/spacing and see what happens.  Please permit me to ask---what is the size of your last image?  Your last image is exactly what I am tring to get---spiraled ducks on a solid white (or black( background)! Thank you so much for your time, Cassandra

Thank you for your reply.  I had a photo of a single duck and did 'select subject' and then followed what I thought was shown on the Photoshop Training Channel and did define pattern.  I then went to  the script and chose 'spiral'--just to see what would happen.  I then chose the parameters that are seen in the screenshot.  The final image was not the view of a large spiral of ducks-----which would have been super, but it was a very compact image of the 'spiraled' ducks.  I will check the image and the pattern's resolution and send an updated reply.  Thank you again---I am quite new to the many options that Photoshop offers.  I have taken a class in basic Photoshop---we did not get into all the details of using the fill options---so much to learn!
