Thrifty or tacky?

Using leftover envelopes from bills that you pay online... the windowed kind? Would you use them to mail things to friends or family? You could use them to hold other things, like seeds or notes or whatever, but would using them for their original purpose - mailing - be just too extremely frugal?

Reuse Fat

Chicken fat used to be prized as a baking and cooking fat; beef fat is also good to use in many ways. When you roast a chicken or a piece of beef, let the pan liquid cool in the refrigerator, then skim off the fat. Clean it by simmering it in a skillet until all the water is gone, then strain and refrigerate. Try it the next time you need fat to cook with.
