A sweet friend told me how to use lots and lots of fonts without installing them onto your computer. They take up lots of room when you install.
First you can download free fonts from the site of your choice. Then unzip them into a folder you can easily access. Next open the ones you think you want to use on a project and LEAVE THEM OPEN. Then after these are opened, open SBM and start your project. When you go to the list of fonts, the ones you have open will appear in the font menu like magic! Please note that this only works if you open the fonts first and then the SBM program.
I have no idea how or why it works, but it does!
