The Carnival of Homeschooling is up at Palm Tree Pundit, and, as promised, it's all about Connections. Sometimes when you suggest a carnival theme ahead of time, the word doesn't get out about it; but bloggers seemed to jump right in to this one. If "Connections" don't interest you, you can sidle over to "Help! I'm holding a haggis!" (And Gung Haggis Fat Choy?)
The Tao of Making Money hosts the Festival of Frugality: Frugality is for Everyone Edition. I think that's a good theme too, because as Amy Dacyczyn always pointed out, there are all kinds of definitions of "frugal." This carnival starts with toothpaste tubes, duct tape and aprons, and moves on to free airline miles and buying rings at Costco. Something for everyone.
The Deputy Headmistress didn't send this post about frugal eating to the carnival (she submitted one about mittens and snowpants instead), but if you're looking for frugal food ideas, it's full of good ideas.
