I'm sure this was already posted but I take my camera to class if I'm planning on learning a new pattern and even use at home. I lay the blocks out the way I want them on bed or floor then I take a couple of pictures with my digital camera. When I;'m ready to ew blockws together I just load up the picture and see what went where. Also works well if you're not sure. You can move, take pic, move take pic then scroll thru and choose one you like best.
