I usually look at
fontseek.com - free fonts search engine, finding font search engine first. But, in this case, "Soap" was not listed. Next, I will usually go to
Identifont - Identify fonts by appearance, find fonts by name and look for fonts by similarity. But, again, no luck this time. As my last attempt, I normally will try to find the font on Google, with the font file name. If it is a standard font, you can find the file name at
Fonts.com. In this case, the file name is "soap.ttf".
Do a Google search, and you will find what you are looking for.
