How do you make your own Theme?

I'm a graphic designer and I want to create my own themes. Is there a program that I can use to do this?

Thanks

Its a giant pain in the arse, but if you are patient and want a new hobby, youll need plazmic..

you can google to download.. i think the latest is plazmic 4.6 I dont remember

Free BlackBerry Themes | Blackberry Storm Themes | Blackberry Bold Themes has a theme building section with icons and help also,

Thanks much! I will have to snag a PC since I run Mac :(

i does take a while to get use to. I am trying it now for my first time and it is a pain

I've found a few that are kind of okay, but I am super pickey about things that involve graphics, so I'm going to see what I can do.

how do you install a new theme?

Download Plazmic and give it a shot. I did this myself a couple weeks ago and managed to create the exact theme I always wanted but could never find (here).

I've found there are two components to making a theme. The theme layout using Plazmic which is actually pretty easy. In just a few hours, I was able to create my theme using available graphic elements. The only custom graphic was the wallpaper which is a photo I took and just cropped to the correct size.

The second aspect is graphic design and making your own custom icons, etc. This part of theme design is entirely subject to what you are trying to accomplish, and how good you are at it with whatever programs you are using.

I use PhotoShop and I've been a graphic designer for years. Will it give me the option for the L shape and such?

As for the icon aspect: Is there a specific pixel ration I should use?
