Hiya Judy
Firstly as a new member - Welcome

The copy film is suitable for Glass painting I have used it myself you can either put it through a photocopier / printer or you can just outline on it yourself but it is not adhesive if you wanted to use this for window clings you would have to find some way of sticking it to the window
There is a clear self adhesive film which I have used in the past to do window clings and it is very good you outline and paint on one side then peel off the backing to enable you to stick it on the window ( when dry of course

) personal preference is to use solvent based paints but you can use the water based ones with it too
Unfortunately it is not in the shop at present, I'm not sure when it will be back in
Hopefully someone from Admin will see this soon and may be able to advise a bit more as to when it will be back in the shop or you could give customer services a ring to find out
Sorry I can't be of more help to you on this one
Take care
Janet
