I am looking to get an A-2 Bomber jacket here soon, and when I get it, I want to have some stuff embroidered on the back as well as on the front.
If you are looking to make your jacket "authentic" as possible, then you
will want to have the back panel painted, and the arm and chest would
have a transfer decal put on, have it painted directly on, have a
painted/leather patch installed, or have an embroidered patch put on.
You really don't want to do embroidery right on a leather jacket. The
place doing it would have to take out the lining or they would be stitching
thru the lining, and that would make a real nice lumpy spot. Not to mention
since the leather does not really stretch like cloth, it would probably
pucker up alot and ruin it.
Also, if it did not come out the way you liked, it will make a million
little holes in the leather, and that would surely ruin it forever.
If you check the Vintage Jacket forums here
http://cornellsurgery.com/v-web/bulletin/bb/
you can do a search of the site, and you will find several guys
who both paint the artwork on the back panels as well as make custom
made painted/leather or embroidered patches for sewing on to the
jackets the proper way.
The guys on this forum are even more anal about their WWII and
other leather jackets than we are here.
They spend upwards of $1200.00 for a real A-2 repro, to the point of
having the correct number of stitches per inch on the seams!!
These guys would never embroider right on one of their A-2 jackets.
Now, if you wanted to have a patch or something like that embroidered
first, you could then sew that onto the jacket. That would be much
better than doing it right on the jacket, and it would be much more
authentic.
