I made a couple of T-shirts for Christmas Pressies this year, they are quite easy to do, just a little time consuming!
you have to cut the design from the garment vinyl in mirror (iron on side up!) It is really easy to get wrong if you do not check before cutting!
this is a little shot of what it looked liked in my Robo software before cutting
and this is what the transfer looked like after cutting and weeding (picking out all of the little bits you don't want in the design)
This is it ironed onto the T-shirt
and this was a little one i cut for Mr Fairy (its on my shelf, still not ironed it onto the shirt!! Rubbish Mrs Fairy!)
