When you have young kids at home... and that you have urgent stuff to do (deal with World Xmas postal chaos for example), i try to keep them busy (let say 5 minutes). so the last idea was to recycle my working material : my stencils.
They are made from pictures, then transformed into black and white picture like a "pochoir" or Stencil. But once i've used them for my drawinside picture iput them aside, creating a useless stack of paper to Recycle.
They prefer to do coloring on cars pictures indeed ! Need to do others car pictures to keep them busy then.
by the way, i have a mustang Gt 2006 on the grill with color, my new year custom project...
