DEAR HELOISE: For those who wear wigs, I always wear a thin cotton headband under the elastic perimeter of the wig. It absorbs most of the oil and perspiration, especially in warm weather. I rarely have to wash the wig, and when I do, I just wash the edges to avoid soaking the entire wig. In my opinion, they never look quite the same after a major washing. I also have multiple wigs that I rotate, which minimizes the need for washing!

I read your column in the Arizona Daily Star.

DEAR HELOISE: Regarding the reader who wrote in regarding how nonsensical it was to have antibacterial wipes at the entrance of a grocery store, I always thought that the wipes were there for the handle(s) of the cart you chose. This way, you can wipe off germs that are left on the cart/basket before you shop. When doing so, you can also wipe off your own hands if desired.

DEAR HELOISE: Former teacher Sara, in Spokane, Washington, could’ve suggested to mix in geography with normal “school skills.” Students in elementary or even middle school could color in maps of the world or go from continent to continent for a few weeks. For middle schoolers, teachers could hold discussions about maps and certain customs in each country. For high schoolers, teachers could present maps that relate to jobs and trades and show where certain things are made.

All it takes is a little creativity. Of, course, this education should also start at home.

DEAR HELOISE: The 5.3-ounce yogurt cups have an easy pull tab on their plastic label, which leaves you with a nice white plastic dish that can be used for so many things. I use them with my dinner plates for fruit salad, desserts, favors for Easter candy, nuts, sides, and crafts. Why throw them out when they have a useful purpose? You could maybe even donate them to others! Do you know of any places who could make use of these cups?

Gayle, this might be a great project for Sunday school classes or anyone who wants to create a small gift to someone else, such as a grandchild for their grandparents. Readers, do you have any other ideas for yogurt cups? If so, let us know at Heloise@Heloise.com.
