Pinwheels on 4-shafts?!

I find myself thinking outside the box more and more these days!  Here are pinwheels done on 4-shafts.  It's an 8-shaft pattern!  How is it possible on 4-shafts?!  Well, I just spend a lot of time picking up individual threads.  It's so tedious, but the good part is it slows me down and keeps me from using up too much yarn too fast!  Slow weaving is good, right??

I hope to work my way up to this project: http://weavezine.com/spring2008/wz_sp08_NancyAlegria.php.  I love the colors!!!
