If you decide to use my themes, the only thing I ask of you is that you keep the credit on. You can edit the themes anyway you would like to, but the credit must stay in tact or I will message you. I spend a lot of time making these themes and it isn't right for you to claim them as your own.

To download a theme:
Click code below the image of a theme you would like to use. This link will take you to a freetexthost page with the code. Copy the entire code and go to the customize page tumblr provides for you. Select "Use Custom Theme" and eventually click "Edit HTML" and replace the old code that's there with the code you've copied. Click "Update" and "Save."
