We found the picture of the orange phone on the internet, printed it onto Transfer Paper and ironed it onto the t-shirt. NB: Instructions are included with the transfer paper.
Choose a design and print it onto Transfer Paper (use an Ink Jet printer).
Cut out the design to your desired shape (you may draw the outline with a pencil first...).
Separate the backing paper from the transfer.
Place the design on the t-shirt and iron it onto the t-shirt. Put a piece of baking paper between the design and the iron. (Turn the iron dial onto "cotton" - fix the print by pressing, moving the iron firmly for approx. 1 minute). Let the print cool for a few minutes. Then remove the baking paper.
Finally decorate with stamp printing using Textil Solid fabric paint.
Find cool designs on your computer or take your own pictures and print them out onto the transfer paper.
