I found this tutorial on the unlucky General blog very interesting indeed!
“I take a fair bit of effort to create my own flags. I see many people’s armies and units whose flags are an afterthought, an inconvenience or a nuisance step in the process to paint up a unit of toy soldiers and get them on that table. I get it completely. Many of us probably think it’s too fiddly or that we feel unable to compete with the level of detail commercially produced flags can achieve through the printing process. In many ways this is neither wrong nor unreasonable but I’d like to make the case for making your own flags and provide a crude how-to for what I am doing these days.” The Unlucky General.
