I have to say my first attempts at transfer printing were a dismal failure and once again I almost gave up on the idea. I was using a product sold as suitable for transferring images onto T-shirts. Well it might work for that but it certainly did not work on my fabric. Then I tried Transfer Artist Paper which I bought here (I think it is also available at Spotlight for Australian readers) and it worked perfectly.
At last, I have my French typography cushions.
