These are the premade stretch headbands. You can buy them at Target or Wal-Mart as the previous post stated.
My daughters love these and they are a hot item for cheerleaders. (minus the flowers of course!)
The appliques you can buy if you search on E-bay. I do have a few of them that she has in the pictures. Maybe I'll glue a few to my daughters headbands.
You should be able to find them with no problem.
