Have you discovered Wordle? It's a website where you can make subway art for free and you don't have to be all tech savvy or anything to use it? I made this one in a couple minutes. I'm not actually going to use this one for anything, but I just wanted to try it out.
This website would be perfect if you're into Subway art for seasonal decorating. Wouldn't it be fun to make a Christmas themed one and put it in a frame?
Make sure you check out the FAQ section before you do it. It explains how to make one word larger than the other and how to save it. It's super simple....SWEET!
