From the photo these sheers look like they are patternless, which is available at any Target, Bed Bath and Beyond, etc. But I found some very cute sheers at Pottery Barn kids and the nice subtle little embroidered polka dots come in a variety of colors:

Best wishes!

The drapes are actually from Lowes!

What is this paint color?

Sherwin Williams hinting blue

Very beautiful pink color.

The birds and flowers pattern also can be painted on wallpaper directly, save time and more easy to install it.
