Thanks for the great advice, everyone!
This story took an unexpected twist. I was telling my sister that one of my to-do items was to come up with 100ish ornaments to make by myself while working 50+hour weeks (it's a home for babies and toddlers, so - cute as they are - they're not much help

).
My sister insisted on sending me $50 for ornaments. Flat-out
insisted. She said that with her husband being deployed, she and the kids have been the recipients of incredible kindness this year and she wants to put some of that back out in the world.
So thanks, Sis, and thanks, Target, for having the perfect ornaments! They have large, sparkly, non-breakable snowflakes 2/99 cents, and smaller ones at 4/99 cents. I grabbed them in pearly white, gold, and red, and I'll just pay myself back with her check. We have PLENTY of ornaments and it will be beautiful!
