I went online and found some photos of Pinkie Pie, Twilight Sparkle and Fluttershy and then using the Silhouette software I traced around the images. This gave me the nice silhouettes. I was going to cut out their cutie marks too but they were so tiny that I decided to pass. I cut the image onto the pink, heat flocked vinyl and ironed it onto a plain white $4 shirt I recently bought at Walmart.
I just ordered this vinyl and when it came I didn't think I liked the colour, I was a little disappointed but once I ironed it and peeled off the plastic it turned out I love it. Especially since the shirt already had that hot pink trim on the neck.
I think my favourite part are the delicate, adorable eyelashes that turned out so well.
