Well if this wasn't so funny

that I did this I believe I would be crying! But I really need some help/ideas.
My first order for tee shirts and I have to put names and numbers on back. I ordered easy print letters from Transfer Express (not really easy) instead of the press and print. They are screen printed onto the paper and i have been cutting them with my paper cutter.
Well I have them all cut out now and there are a few huge problems!! They are not evenly cut...ie some have extra at the top, some have extra at the bottom, etc and when i place them on the shirt to press I won't be able to see through the paper backing to line them up!!
There are 27 shirts with names that I have to do and now I must figure a way to get them on the shirt evenly with uneven frickin letters!!
My thought is to trim each individual letter again to the bottom so that they will be as close to even as possible, which will take me some time or to put them on a light board (which I will have to buy), line them up, tape them down and then press or IDK what else!! What about spraying a piece of paper (don't know what kind) with a light adhesive, lining up letters, pressing them and pulling off both backings???? Have no idea if this is doable.
Like I said, I am such a newbie that if this wasn't sooo funny I would be crying right now!
I don't have time to reorder press n print letters either so any help would be appreciated!
I hope that I have given you all a giggle on this beautiful Thursday!
Please reply and rescue my dumb butt!
Live and learn....I'm sure I will make plenty of mistakes, but as long as I can keep laughing I'll get through it......at least I hope so.
Thanks!
