What's the Name of That Book??? discussion

Fairly sure it was a childrens book, with quentin blake style illustrations, but all I can remember is a little girl living in some kind of tower, either gets sent an eiderdown quilt, or sends an eiderdown quilt herself, in the post.
I've been trying to find out what it was for years, every now and again something reminds me of eiderdowns, and this memory bothers me for days (until I forget about it again).

A long shot because the illustrations don't seem similar to Quentin Blake, but I'll mention it in case it triggers some memories. The Sea Chest by Toni Buzzeo? The girl lives in a lighthouse and her family discovers a sea chest filled with a quilt / blanket and a baby.

Poison, around what year did you read this book?
Did the girl live in a lighthouse, perhaps?
Who did she live with?
Was it like a fairy tale (e.g., trapped in a tower) or more realistic?

No, not that one I'm afraid.
I have no idea when I read it, probably some time in the mid to late 90s? And I'm afraid that's literally all I remember about it

bumping - sounds interesting

Poison, are you still looking for this or did you find it?

No response, moving to Abandoned folder.
