Q: Is there a way to preserve fall leaves for crafts projects?

A: Leaves dry out and curl, making them a challenge for crafting. Their vibrant hues also tend to fade. Using a plant press (or a heavy book) is one way of preserving them, but they will become brittle. To keep leaves both pliable and bright, you can soak them in a mix of water and glycerin, which can be purchased at crafts stores and pharmacies. This process will keep the leaves supple and close to their just-fallen shades: Yellows become brighter; reds and oranges turn ruddy brown.

To preserve leaves using this technique, first wipe away moisture or dirt. Mix two parts water with one part glycerin. Layer the leaves in a pan. Then pour in the water-and-glycerin solution, immersing the leaves. To keep them covered, you can weight them with a plate. After four or five days, remove the leaves, and wipe them clean with a soft, dry cloth.

Q: I just moved into a new home and need kitchenware and linens. Can I register for my housewarming party?

A: Traditional etiquette frowns on such a registry, but many long-established societal rules don’t always make as much sense as they used to. Once upon a time, marriage and a home often went hand in hand. Today many people move into a house of their own while single; they have as much need for household items as newlyweds do.

If your family and friends have said they would like to buy you gifts, creating a registry or a wish list at a store may be helpful. Give the information only if asked; don’t include it in your invitation. If you do register for your housewarming, it would be wise not to do so again if you get married, lest you look greedy.

Q: Are antique lead crystal dishes and glasses safe to use?

A: As long as the pieces aren’t chipped or scratched, it’s safe to serve most people an occasional meal or glass of wine using your heirloom crystal. The amount of lead transferred into wine from a crystal glass during a meal is below the level deemed hazardous by Health Canada, Canada’s national public health department. Children and pregnant women, however, should never use lead crystal.

The danger comes with storing food or drink in lead crystal items; according to the U.S. Food and Drug Administration, this should always be avoided. Over time — even just 24 hours — damaging amounts of lead can leach into the contents.
