I learned that trick at a scrapbook class: get white words and color them with an inkpad to match whatever you need. This is a nice size for cards and great font.
I have not used these particular titles from Doodlebug before. I am not sure if I will buy them again. They are a little difficult to manipulate to adhere them to a project. It could be just me though. As I am a senior citizen, I find handling small items such as these is not easy for me. The words are thin, making them more difficult to use; but they do look good on dark colored papers, etc.
