They're very pretty.
Blossom has a lot of hair for a Peru or Nirvana in general still. I am pro-rehair on Nirvanas when they really don't have a lot of hair, as in a buzzcut or something super short, which is sometimes a minority opinion, but Blossom there is GORGEOUS and has lots of hair.
If the flat-iron treatment scares you, you can try the boil-hair method. It's very easy. You set out a towel on your counter, a good bristle brush, and you start yourself a pot of hot water and get it to it boiling. You can work in some conditioner into pony's hair and then dunk her hair into the hot water and swish it about for about 5-7 seconds, then pull her out, and then brush the hair flat on the towel and it will work the frizz out and straighten her hair. Repeat until you stop getting results. I have used this on a couple of nirvanas, Mexicans, Italians and Spanish ponies, and it's worked wonderful. If Blossom responds to hot iron, she should respond to boil treatment.
