Webby looked at her collection of yarn and string. She had three spools of black (she kept misplacing them). Then there was a number of skeins encompassing just about every color in the rainbow (Granny had spent four years trying to teach Webby how to knit with moderate success until they decided to switch to crochet, which suited Webby much better). To the left was a small pile of purple and pink (they were her favorite colors, after all) and a skein of novelty furry yarn (much harder to use than you'd think). Finally, there was a collection of metallic yarn from when Webby had decided to crochet herself a suit of armor (an undertaking that had made a lot more sense when she wasn't allowed outside of the Manor).
Webby carefully selected a skein of yarn, cut off a length, and attached it to her board. She added a label with a matching-colored marker and stepped back, happy tears in her eyes, to admire her handiwork.
A golden string now attached Mr. McDuck's picture to her own, captioned "honorary niece."
Author's Note: Why does Webby prefer crocheting of knitting? Simple: because I do.
