your thoughts on pinwheel orientation, please. i have been wanting to work on something simple like the pinwheel block. i have been studying many pix on the net. i would like to hear from those who see/don't see a difference in the way these pinwheel's "wheels" are situated. some move left and some move right and some look as though they ARE moving......??? has anyone else noticed this? Help! and thanx in advance for any explanation you can offer!! or do i just need to close my eyes and make them go away?
