I use all kinds. It can be a butterfly stencil I use in my quilting, or butterfly fabric I put in my quilt. For my sons 21st BD I made him a patriotic type quilt as he was in the military. I named it 'Freedoms Peace'. I quilted doves all over it ( the only doves I put in the quilt). I substituted 1 dove for a butterfly. Its been 4 years now and he still hasn't found the butterfly.
