Sorry, my mistake for not being specific enough.
I am running Excel 2007. What I would like to be able to do is:
a) Select a cell
b) Go Format, Format Cells, 'Fill' Tab, 'Pattern Style' dropdown
c) Add styles here of my own devising.
Is it possible to create these styles (for instance in Paint or something similar) and add them so that Excel can use them a a cell fill pattern?
Thanks
