This question already has an answer here:
I opened a new file and created my pattern, selected all and defined pattern. Then I closed the file without saving it and then used the pattern - great.
Now is there a way to make changes to that pattern?
The real problem is I need to used that pattern on my css, Though I can not remember what dimensions i used, so if I could edit the existing one, then I could just save it as a jpg and use it in my css Thanks
