Like those above I've used them as well, the ink jet ones, and can confirm that if you follow the instructions they work well. Just ask my grandaughter, she has them on her Christmas bike, and they are still in place!
I also have used the lawn cloth for sail making – excellent results, and made my own flags too.
I've also used their wood veneer, again ink jet printable, and after some trial and errors, find this excellent too for some projects, like scroll boards on my thames barge for example.
To avoid waste, fill the page with as many variants as possible, and make copies too in case of damage when fitting or in use.
Happy modelling, Kimosubby
