So we're doing a group cosplay of Team Fortress and I thought I'd make a tutorial of how I made my patches for the others in the group. I considered having our patches embroidered, but this looks nice enough that I'm happy with it Important note:
this is a technique that's really super awesome and can be used for any kind of patch, or really anywhere where you wanna attach a fabric design to a different fabric. I've used applique to make Darren's Akatsuki cloak, and for many other things. Deviantart has a bunch of good tutorials on the subject, that's where I learned about it, so if you wanna know more just do an 'applique' search!
Some tutorial mention using freezer paper or something... I don't think you can get that in SA, so I always go for applique paper (available in fabric/craft sewing shops). It's pretty expensive, but truly worth it!
I'm by no means a pro on the subject, and I encourage you to take what you want from this tutorial and adapt what you learn to suit your own project needs!
