[We] got [our] five-patch set. Is there a manual on how to apply them?
TL;DRThe patches are iron-on or sewable, with a small sewing kit included; suggestions include ironing from the back of the fabric or paying an embroidery shop to attach them, especially to curved items like hats.
It's just an iron-on. You can iron on or sew them. And if you just Google ironing on patches... I'm not sure if you need to put something over when you put the iron on them or what.
I will tell you what I did with mine. I got the original Army, Navy and Marine patches, and I got them put on hats, like the old military hats. I Googled embroidery and took them to an embroidery/seamstress place, and just gave them and said, would you put these on, someone who knows how to do it, and it was like $8.
But you can also iron them, or they come with a little sewing kit.
I think when you do a hat, because it's curved, the iron is going to pop up.
I've seen people turn their shirts inside out and iron on the thin side.
Yeah, iron it from the back then.
