I already love the blog Remodelista - but I just found another reason to love them even more. They have an index page called domestic science for all of those very cool, but hard to find household items that make the work of keeping the home up a little easier and more pleasant (and it doesn't hurt that they are really nice to look at, too). Check it out.
However, my all time favorite source for simple, inexpensive and useful tools for around the house is Lehman's. I bought my very first iron skillet from them, and now I am eyeing their clothesline supplies.
