What is involved in Designing own clothes?

[irish-deutsch.livejournal.com]

Started but didn't complete a Fashion Design course a few years ago....due to lack of home equipment I couldn't complete assignment...just wondering whether anyone here has attempted this and if so is a skill which can be learned by an average person with effort?. Am somewhat creative...wouldn't say very...but a bit yes...like colour and things unusual....!

Thanks
A
