ive only done 2 colour t shirts with vinyl but a lady has asked me to do a design on a tshirt which will cost me to much to do it in lots of little bits of vinyl, its only for a 1 year old so will be a cotton t shirt so my question is how do I do it I have sublimation printer etc but haven't seen anything which wont wash out within 4-5 washes so whats my best way to do it
