Thank you all for these comments, motivates me to get to work immediately again
@ Jensen : need some drilling?
@ Foxy and HB : I will try those blue, pink and desert colors.
@ Marilyn : hehe thanks to you!
@ Rukya : yes, I admit this border is actually a wrong cut of the basic template. I thought it could still look nice... But you're right, it doesn't seem very realistic for a military cloth, and I now know how to correct that.
*Plunges in all this again*
