Plenty of adults enjoy arts and crafts every bit as much as the younger set. Recognizing this, Hot Pots!, a paint-your-own-pottery studio, has come up with special packages for birthday parties, bridal showers and plain old bonding. Now kids of all ages can indulge their inner Picassos, using cups, saucers, plates, bowls and figurines as their canvas. The staff provides instructions, supervision, advice and all the paint needed to create a mini-masterpiece -- and for birthdays, a commemorative plate signed by all the guests is provided at no additional charge. Color them beautiful.
