We both make our own decals, mainly to go on our fast electric boats, anything that you can print on your home printer can be made into a decal.

The reason for not using this on the crash tender is that they really need a coat of lacquer after been put on the boat and I didn't want to do that.
But be careful if you go down this route, you can end up with all sorts of daft things on your boat 😁
Grace, who is titch? doesn't happen to be a big fella does he 😁
