Hello mfp1028
I think that planting
thuja seeds would not be a good way to approach growing a bonsai. But there are are some examples of collected thuja that can make very good trees. Some are a few hundred years old and have really interesting trunks. This makes dealing with their unruly foliage a little more palatable.
You can see a few venerable trees if you do a Yahoo! search on Thuja+bonsai:

Political commentary aside, very few questions here on bonsaiTALK go unanswered.
