The enlisted corps gets a clothing allowance every year, but usually, it’s an extreme honor to sew one’s new stripes onto his/her own uniform.
But, I speak on behalf of a group I’m not a part of. I’m just making an observation.

And I don’t mind taking the honor of “punching” those stripes on someone. 
Good job! So you have to pass a written test? They should do that in the Army, too! Is a promotion board part of the process at all?
I didn’t have to take a test, but I did have to go to the board. I maxed it out with a 150pts! I guess it’s kinda like a test, because they ask you questions, but it’s very subjective.
Anyway, Congratulations!!!
In the Air Force, we do it differently (of course!). A 1Lt who’s been selected for promotion will be a Captain-Select, or Capt (s), but you still call him “Lieutenant.” Likewise, majors-select are all referred to as “captain” until they pin on. The only difference is with a General-Select, who is approved for the promotion loooong before the Senate confirms them for the star – in that case you call them “Colonel” but always address them in writing as “Brig. Gen (s) Lastname” and extend them the customs and courtesies a general officer would receive.
Last but not least, the plural form follows the convention of “sergeants major”, e.g. “captains-select” instead of “captain-selects”. If you want to say it a different way you can say “captain selectees”.

Does that mean that if someone has new stripes then you get to hit them on the stripes?
Suppose you can’t sew, is there someone that will do that?
And let’s say you make sergeant. What do you do with your corporal stripes? Keep them for a souvenir? Destroy them? Turn them back in?
So can you get the mods to change your name to Sarge Doors, USAF
To hell with doing my own sewing, it looked like ass. I paid to have mine done when I was in the Navy.
Then there is time honored tradition of “tacking on.” With each stripe all those of your new rank and higher would (or could, not all did) give you a shot on the arm. Depending on how big the command was and how well liked you were it could be a painful day. I’ve seen guys with a bruise covering their whole bicep. I was on an aircraft carrier, that was a long couple of days.
I never heard of an officer joining in.
So ::::TAP:::: from a senior E-5.
Stopping in to wish you luck! 
Usually, we don’t, but there were a few times that the “gauntlet line” was forming, and the shop NCOIC said, “Hey Cap’n, c’mon in!”
But they don’t ever call 'em “Sarge” in the Air Force. That’s strictly an Army thing.
