They do make that blank in black and it will be sharp for this purpose.

This is the pattern. The ribbon can be seen at http://usmilitary.about.com/od/armym...ss/swasm_2.htm Don't let it throw you that it is listed as an Army ribbon. They are identical fo Army, Navy, etc.

The Southwest Asia Service Medal’s ribbon is 1 3/8 inches wide and has fifteen stripes. The first stripe is 1/16 inch of Black followed by 1/8 inch of Chamois, 1/16 inch of Old Glory Blue, 1/16 inch of White, 1/16 inch of Old Glory Red, 3/16 inch of Chamois, 3/32 inch of Myrtle Green and a center stripe of1/16 inch of Black. The next stripe is 3/32 inch of Myrtle Green followed by 3/16 inch of Chamois, 1/16 inch of Old Glory Red, 1/16 inch of White, 1/16 inch of Old Glory Blue, 1/8 inch of Chamois and 1/16 inch of Black.

You will find it best to wrap from both ends towards the middle. Mark out your ribbon at 1 3/8" long on the blank and get with it. Use CP to lock the wraps in place as you move along and pack well.

Good luck!
