(Well past Halloween, I know, but I have been extremely busy) I am not finding the final picture of Mater in his TMNT costume, but this should give you a pretty good idea. I used acrylic paint. The white shirt and grey pants (all I could find) were dyed; thinking about it later, I could have just dumped acrylic paint into a bucket of water and let them soak (rather than use actual green dye). I kinda forgot that they were soaking in the bucket, so they ended up soaking for an extra hour and turned into this olive green color, but that actually is perfect for a ninja turtle costume. I free-handed everything. The band on the both the front and black was orange.
