Etsy and the most amazing transfer artist paper (TAP)- thanks to Cirque du Bebe for the tip off!!! It is amazing stuff - you can now purchase it in Spotlight, it was on sale so it cost $3 per sheet. Apart from the shirt being mighty wide compared to Josiah's Bonds shirts, I love it!
When I printed the image onto the TAP - I then cut around the balloon to minimise the amount of polymer showing on the shirt... (instead of a A4 big square). I did have a blonde moment thinking the white would show up in between the balloon strings but as you can see it doesn't. It irons on clear just as the instructions say! I really should read ALL my instructions. The other thing I love about Lesley Riley's transfer paper is you can draw on it and iron on!!!! Imagine the possibilities :-)
