Awe, mom....you "done good" raising that boy. I was nearly in tears.
My son-in-law is in the Air Force, and he would tell stories of the guys having "princess" sheets sent to them by their loved ones because it would remind them of home and their families (children). If having a "less than perfect to you" quilt makes him think of anything positive at home, it is a WIN-WIN for both of you!
Stay strong, mama. He will return to you! And his service is just one more thing to add to the growing list of why you are proud.
Good job!
