Water colour card using a mask

A Facebook post asked the question 'where can you buy freezer paper to use as a mask?'  I googled alternatives to freezer paper and found one suggestion to use the outside wrapper of printer paper which is exactly what I did and it worked with no trouble at all.  You will notice a slight imperfection on the breast where I obviously did not iron it well enough.  My first time water colouring as well and must say it turned out pretty okay although while wet, it looked a bit crappy.
