First, I'd recommend downloading this:
Gimp (http://gimp.com)
Some type of art program is necessary for making a preset.
After you download Gimp, follow one of these tutorials:
Rimfrost's Preset Guide (http://www.feral-heart.com/index.php?option=com_jfusion&Itemid=2&jfile=index.php&topic=8149.0)
Official FH Preset Guide (http://www.feral-heart.com/index.php?option=com_content&view=article&id=9&Itemid=16)
My Tutorial Bin (First is Presets) (http://www.feral-heart.com/index.php?option=com_jfusion&Itemid=2&jfile=index.php&topic=40939.0)
If you have any questions, PM meh, or post here. o3o
EDIT: Like Shasta stated, try a simple pattern first before you dive into abstract patterns and complex scripts.
In the tutorials, it's very important to save the presets how they tell you to.
This is what I do,
1. Download preset ZIP file
2 Put everything in desired folder. (Like if the download folder says preset#)
3 Get on feralheart
4 Go to tools
5 Preset maker
6 Click the desired number
7 If it is white/yellow black then you did something wrong.
Star wants to know how to make a preset, not download. ^^
Like how do you get the patterns on one body part or how do you get a specific pattern and color, this is all confusing to me
Just look at ze tutorials. ^^
1. Go into Gimp.
2. Open C: >>> Feralheart >> my_presets > references and open one of the UV(s).
3. Color it in! Draw whatever you want on the preset part.
4. When you are done coloring it in, go into (IN GIMP) file > export, and export what you just colored to C: >>> Feralheart >> my_presets > preset_3. NAME/SAVE the body part as:
preset_3body.png
(^Or whatever body part you just colored. Head, tail, body)
SAVE AS A .png FILE FORMAT!
Then go in-game to preset maker and test it.
