Collect images of tattoos you like or research different types of tattoos to give you the best idea of what you want. Remember, a tattoo is for life (unless you want to have extensive laser removal surgery) so you need to pick a design that you are completely happy with and a design that represents you.
Find a website that you find easy to use and a website that will allow you to design your own tattoo. Try createatattoo.com or straytats.com. Both will allow you to upload your own designs or pick from the pictures in their galleries.
Move the images about on the web page until you are happy with the position that they are in. You can then customize and personalize the tattoo. For example, you can add names, personal graphics or change the size. You can also overlap the designs, if you feel this would work better.
Save your image. When you think you have a final piece, you need to save your work so you don't lose it. Both createatattoo.com and straytats.com will allow you to do this. Click "File," and "Save" to save the image you are working on and it will save to your computer. It should be saved as a .png format.
Pay for your design via the website's "checkout" button. You will need to follow the instructions online and pay using a credit or debit card. Your design will then be shipped to you and you will receive it within a week. You can then take the design to any tattooist and ask him to apply the tattoo.
