I have had those zips for a long time and was thinking how exactly to make the design with them. So I made an attempt today, but not really successful I think.
Colours matched very well to be honest but I was really in rush to finish so I could make them excellent.
I have used Barry M Papaya 304 Jelly Hi - Shine in two coats. Then place the zips and sealed the water transfer decals with Seche Vitte top coat.
