if you go the inkjet paper way make sure you get the right paper.
Standard iron on transfer paper for inkjet printers comes on transparent carrier film and thus allows the colour of the garment to show through. This is okay if you have a white garment of any other light colour but a bitch when you try it on a black garment. this is because ther is no white ink in a printer
If you are trying to print onto a dark garment you need to get hold of dark transfer type paper. This has a white carrier filmn and so lays down a white background under the print that you have done.
this stuff looks cool if you spend some time over laying it on( you iron it on and peel the backing off when the design has cooled)
and is the easiest and cheapest way to do custom logos for teams.
the media cost about eight quid for ten a4 sheets
