Changing fills

[gbredon]

I would like to create a landscape drawing that contains lawn and paving. If I use a textured fill such as the one in the attached xar file it is the wrong scale for the drawing I have done. In this drawing I initially put in a solid green colour and then applied a fill as a transparency. Is there any way of scaling the grass blades down to their appropriate size?

Or possibly does anyone have any suggestions as regards doing this in a better way?
Thanks in anticipation.
