Also, the sheets they have are so dingy and old ( I'll post photos of the girls' rooms below) that I can't help but think a 'sheet drive' is in order! Remember, their pillows are a different shape than ours, so you cannot send pillow cases. They will not fit. But twin fitted sheets and flat sheets will fit!
Here are some photos of one of the girls' rooms, so you can see that they DO have bedding . It's just that the boys are, well, boys -- they prefer the ease of no sheets. Saves them from the extra effort of making their bed! But I DID get out of them that if they had 'cool' sheets with cars or soccer balls, etc on them, they would make the effort..lol!
