good meathods for short hair?

ok. i want to get enxtensions just to see what long hair is like. im looking to buy the extensions sold at sally's beauty supply. keep in mind, my hair is only about 3-4 inches long, so i was wondering what install meathod was good for me. i was looking at clip-ins for the bottom, and some other meathod for the top. what do you gals think? i want to be able to do right up to the part, and have them look halfway decent. so i think shrinkies are out.

thanks. i was only considering clip ins for the bottom and back, cuz i cant see the back, and seing as this is my first application of extensions, i figured this would be easiest. i would like to do shrinkies on the top, and front of the sides, but i dont want them to show. most women have longer hair when they get extensions, and as ive said, i only have 3 or 4 inches of real hair, so im concerned about the shrinkies showing and looking too unnatural.
