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 pictureofanelephant 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 pictureofanelephant 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 pictureofanelephant and pictureofanelephant 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 pictureofanelephant 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 pictureofanelephant 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 pictureofanelephant 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.
