LOL this exact pony, I'm sure I have photos someplace, I remember because I did her tail with a toothbrush! I wet her hair with hot water, put paper towel over, and held it down with hair ties for about a month! She's gorgeous now, and she's even been in storage for a solid while at one point, and nothing shifted.
Edit: Found the photo! I must have taken it as a demo for someone, because I've already taken the paper towel off, and her hair is dry. I must have re-positioned the band and toothbrush without the paper beneath, just to show what I did. remember though, to prevent any rubbing or colour transfer, use the paper towel!!
(sorry guys if this doesn't work, Imgur wouldn't upload it, so I used the one already in my photobucket. If it goes gunky I'll remove it!)
