Some people wanted to see the way I make kimono patterns, so I'll submit this.
But as you can see, I don't do any special thing, I just draw and color them.
I refer to kimono magazines or so on.
If you would like something like that, you can see many kimono patterns at
japanese yahoo auctions.

I hope it helps you.^^

Edit:
About the part I couldn't explain, translated it for me!
Bellow is the explanation:
first they'd have to draw the pattern, of course. Select the pattern and then go to Edit>Define pattern and give the pattern a name.
to fill the pattern into an area, it's Edit>Fill> Pattern and then they just select the pattern they want from the drop-down menu on the side ^^

Thank you Maria-san~~*^^*
