I made the design in Inkscape so I could draw the flower and adjust the text how I wanted. I printed several designs on plain paper to get a feel for how they would look. At first I had coloured flowers but I'm glad I went with black and white.
I made the label specifically to fit on some white ribbon. First time round forgot to reverse the design before I printed it so the text was backwards. My fault for not reading the instructions! The transfer leaves a white backing over the whole area which is a bit of a shame but that's not noticeable when they sewn in.
