As suspected, no one really asks for her input, which is fine because she doesn't have much to say. Most of the preparations had already been completed, and the turnip carving served as a menial task for a group of teenage brides missing their Hogwarts days that could have otherwise been completed by elves. Bilquis mentions in a whisper that the preparations were more of an excuse to gather and gossip at this point than an opportunity to actually get anything done. Hermione doesn’t doubt it.
