Do not store or display works of art in areas of potentially high humidity or water leakage, e.g. basement, bathroom, outside walls, under pipes. Avoid areas where temperature and humidity fluctuate, or where there is inadequate air circulation, e.g. attic and places listed above. Do not hang artworks over or under radiators, heating and cooling vents, active fireplaces, humidifiers, and vaporizersA. The hygroscopic nature of wood means that it will take water from the atmosphere and expand, but it will contract as the humidity lessens. The direction of shrinkage is almost always around the circumference, which causes a solid piece of wood to crack vertically. Keeping it in a steady relative humidity can stabilize the sculpture; if the wood does not absorb or release moisture, it will no longer expand or contract.

Sheila also did collaborative printing with Rauschenberg, Frankenthaler, Motherwell, Arakawa, Segal, Wegman, Shields, and many others. In 1990 she was honored with a 25 year master printers show at Rutgers Zimmerli Art Museum in New Brunswick, New Jersey. In January 1994, assisted by artist friends, Sheila developed a new monoprinting process utilizing the silk screen medium, yet enabling the artist to work directly on the silk using almost all of the drawing tools they are used to using on paper. Art on the Net is a collective of artists helping each other to come up on the Internet and share their works on the World Wide Web. Artists create and maintain studios and rooms in the gallery where they show their works and share about themselves.

What is the cause of dark spots that sometimes appear on the paper of drawings and paintings? Reddish-brown spots are known as "foxing", caused by mold or the deterioration of the metallic impurities left in the paper from the manufacturing process. Other colors of spots may be one of many types of mold damage. Mold spores are everywhere in the environment, and mold thrives on cellulosic materials, especially in conditions of high humidity (above 65% of relative humidity). Keeping artworks out of high humidity areas like bathrooms or exterior walls, can help reduce the development of such stains. If I have a work of art on paper that appears to not be flat, should I be concerned? Paper is hygroscopic, reacting to changes in climate by expanding when it is humid and contracting when it is dry. A gentle undulation in the paper called "cockling" occurs under these conditions, especially with larger works. This may impair the work aesthetically as well as cause mediums such as gouache to crack or flake as it is unable to expand and contract as the paper itself does.
