At Christmas I bought a couple of packets of very cheap felt from the hobby shop to make stick-on reindeer noses and eyes..... don't ask.
It occurred to me to try printing a rug on the white sheet that was in the pack it they looked to be the right size for the printer and seemed more 'stable' than ordinary felt fabric.
So, OK, it is a long way from perfect but it is as good as any I have paid an arm and leg for. Indeed I might be happier that it is not so bright as the paper version lying on top of it. My husband did say the colour could be increased and I could tweak this and that to get it better, but for now this will do just fine. I may have another go when I have time. It was good enough to know it can be done without bunging up the printer and exploding my other half's brain.
Moral of this story is - if you think it, try it, you never know your luck.
