Hi, Janet:
I had made a welcome sign and a customer requested it in Spanish. It took me a couple of hours to figure out which font I used for the original sign. I do my stuff in Adobe Illustrator and when I am working with the lettering, I usually need to convert it to vector so it is no longer read as a font, but rather as vector line work. I rarely use a font without making changes with it so it is able to be cut. This also helps when I send files so that there is no missing fonts, as you are turning the letters into objects, but it does create a problem because it is no longer type and you can't change anything or see what font you originally use.
After finally finding the font I used, I now type on the page the name of the font on the artboard somewhere off to the side. This way if I need to go to the original file to change it, or even if I like that particular font and want to use it for something else, it is right there for me to read. I didn't go back on the older patterns, but from now on that is what I will be doing. Better late than never, I guess!
