Transfer paints samples

Working with the drawn images, I experimented printing (again) but using fabric transfer paints….the colour turned out bold and bright how ever- the lines were not straight and there were smudges. I will have to try some out possibly using a screen, printing onto paper then ironing the image onto fabrics (maybe ones with existing patterns on them as I had tried before- might be more effective with transfer paints because there brighter).
A bit of an issue I ran into while doing the other samples was that the transfer paper and the transfer inks work better on synthetic fabric rather than natural ones, these and the previous transfer paper samples are all printed onto 100% polyester.
