I'll put in a vote for the game Sleeping Queens. My daughter is also really into coloring and drawing. Perhaps some multi color pencils, sparkly pens, etc.

Duct tape in fun patterns and colors. My DD love to make wallets, coin purses, and handbags, plus using the tape to decorate stuff.

My 7 year old loves books about horses, cute pictures of any animals, shopkins, calico critters, smelly markers. The Disney store in Tysons has cute nightgowns, like Sophia the first. If you are there, the store "Justice" (yes, it's awful) has things like pillows and water bottles with a letter - so say her name is Sophie, you could get everything with a S on it!

So kind of you.

Make-your-own jewelry sets

My 7yo likes Beanie Boos, Barbies, and crafty things.

Any of the melissa and doug decorate sets, such as a jewelry box, how to draw books along with a sketch pad and colored pencils, the Creativity for Kids sets such as make your own perfume or lip balm,

My 7 yo likes Lego Friends sets, Shopkins (these little plastic figurines), Playdoh sets, and those color it yourself purses. She also like card and board games.

My friend's 7 year old daughter is undergoing cancer treatment and I would like to send her a little care package. I do not know the girl well but know she loves the color purple. What do 7 year old girls like these days?! Thanks!
