Thank you! I just pulled small pieces of red clay off of the block, rolled them into little balls, and then pressed the eraser end of a pencil into them to make the indentation. Baked them for about 10-15 min and then dropped them into a bottle filled with clear glue. It was really pretty simple.
Your reap was wonderful! I had to stop by and say how impressed I was with the red blood cells! I've had that project pinned for quite a while but never thought it would actually work. They look incredible!! I've bumped that project up now for my mad lab. Any tips or tricks you want to offer? Thanks!!
