It was quite tricky attaching such a big self-adhesive vinyl print. For my first attempt I cut the sheet exactly to the size of the panel but then I couldn’t avoid getting fingerprints under the edge where I peeled off the backing paper 😦
So, print another and this time leave plenty of extra material around the edges, especially at the short sides. It’s important to try to get the vinyl stuck down straight and not to let it develop any creases – stick one edge down and peel the backing off as you go, smoothing the vinyl down with a soft cloth. Even then I got a couple of air bubbles but managed to smooth most of these out at the edges; one or two little blemishes but I can’t be bothered to do another one!
