^ Hmm. I guess I would recommend going to your campus library and seeing if their computers have a newer version of Microsoft Word. I don't really know what to tell you! If by "layered patters" you mean the two-layered letters, you can make two stencils, one being a bit larger than the other, for the background letters. Or, you can buy iron-on letters (can probably found if you google "(GLO) gear") and use those to trace smaller/larger ones on your desired fabric to make shirts.
Sorry if I'm missing your vision completely haha
