My pleasure! It's something I've been thinking about doing for a while.
Real tie-dyes run, but this didn't seem to. In a warm wash, I had accidentally washed a pair of white socks with the shirts (I did the Mickey shirt separate from the other two shirts I ended up doing. So the socks survived two washes), and the socks came out fine.
I bought the Tulip stuff at my local Michael's, and they had both kits and separate bottles (boxed, hense not knowing the bottle plan). I could only find the lime green in a three-bottle kit, and bought the red and blue (they called it turqouise) separately. I also bought soda ash, to pre-treat the shirts.
After the project was done, and seeing how it was a different technique than what I expected, I think it may be easy with the bottles just to draw the face and make three circles just like that.
Otherwise, doing it the old-fashiond rubber band way, I would guess if you can bunch the head so the three rubberbands are almost touching (the two ears to the head at least), it may come out about right.
I don't know about doing the shirt in segments, as it may make the ears a different color from the head and you're supposed to wash the shirts after they've sat and settled 4+ hours. It seemed it would be a very messy thing to try and undo-redo the bands mid dye, too.
