WOW, Arnaud, I'm now jealous....you have mastered cutting and sticking these PVC strips too!
We both know it isn't easy until we tried and the result is so satisfying since they look so original and believe me these are very good quality and you can leave it in the sun and if it fades too soon, I'll go after my supplier
(those I used on my ACW many years ago still looks the same and I just wash them in water without any worries)
so far I've only made 2 layers of 'collers but they do sometimes use 3 layers even, right?
....oh, yes, they come in so many shades (I think I have about 5 shades of blue and still not ebough to match all our PM shades of blue) ....
