Here's another of my occasional posts featuring home-made flags produced with PaintShop Pro - as ever, it's stuff I've been working on for myself. If these are any use to you, please be my guest. Right click on the image - open the link (bigger version) in a separate window and save.
If you print the entire image so that it is 120mm high, the flags will be the correct size for 1/72 or 20mm.
These are deliberately far lower resolution than, and therefore inferior quality to, my previous efforts, but I found that at 20mm scale you can hardly tell the difference, so these are from Cheap'n'Nasty Productions Inc - not recommended for 54mm armies.
A few of these are specific units, as identified, some are pleasing generic things I borrowed and tweaked, some may even be from the wrong century - it's OK - Cheap'n'Nasty have a certain standard to maintain...
If you like them, you're welcome to use them. As ever, the tasteful green background is just to make it easier to cut them out!
