As her pet name is Chouette (Owl), I promised my Sweetheart I would make her an owl costume months ago. And lucky for me, it fits into Nancy-Raven's party theme: she can either be Athena's Owl (my Sweetheart has suggested I go as Athena and he could be Odysseus - that would make a nice family costume theme), or she could be Blodeuwedd in her owl shape; either way, it works.
And so for research: I began googling "Baby Owl Costume" and found this adorable one:
It is adorable and seems very well made, but I want a snowy owl. So inspired by that one, I have bought her a white velour coverall as a base, and I intend to make a white and gray version of the above costume using Simplicity 2788, View C (the Lady Bug) as a base.
From that pattern, I can easily modify the wings' shape to fit my needs, make a round hat to which I can attach an owl's face, and of course, add bands of "feathers".
And for her feet...
