Ginny's presents! Ginny got her mother these mittens, which, although admittedly not all that practical, she thinks are adorable. For Arthur, she found a hand-held metal detector in a sale bin at one of the shops in town, and bought it mostly because she couldn't figure out what the hell it was for and she figured he'd enjoy that.
Bill, Charlie and Percy all got a package of homemade Christmas cookies. This isn't Ginny's first ever attempt at baking, but it might as well be. She's no Molly. She's sorry.
Fred and George each got a spectacularly annoying singing card (it'll keep going for at least two hours) with a promise to come visit - and a threat to beat them both up if they don't come and take her out to London someday over break.
And Ginny would have loved to get her classmates something, but ... well. She's a Weasley. Those mittens broke the bank, guys.
