Drawing glove for iPad
From a FAQ of Smudge Guard:


  Unfortunately, the current SG gloves are not compatible with the iPad
  at all. The SG glove does not prevent detection on the iPad. :(
  
  However, please note that recently, two other customers of mine bought
  the SG glove and tested it while sketching on the Autodesk Sketchbook
  Pro. They said it did not prevent accidental strokes with their palm
  because the material/fabric was not thick enough. But cleverly, my two
  other customers then tried slipping in a microfiber cloth, (folded in
  half) into the side of the glove. The microfiber they used, were those
  little rectangular shaped cloths that are made to clean eyeglasses.
  They inserted it into the glove (where the edge of the hand is) and
  they said it worked! The iPad didn't detect the side of their hand.


There is also an info they started working on a fully-iPad compatible glove. Microfiber option could work with any thin glove, perhaps.
