A search on "red cedar bonsai" usually turns up one or two very nice specimens----and that's about it. There's a reason this species has no real "great" specimens that have been worked on for years. It sucks as bonsai material. The results above are not typical and require a lot of know-how to achieve. Red cedar in the wild is mostly telephone pole shaped with extremely uninteresting trunks and the foliage is a beee otch to work, since it persistently reverts to prickly unmanageable tufts at the ends of gangly branching. It's pretty far from "friendly beginner material." It's just common and readily available to waste time on.
Sorry to be negative. But you likely have species that are exponentially better as bonsai all around you in Kentucky. Hornbeam, beech, crabapple, pitch pine, hawthorn, even Va. Pine (and a dozen others are more easily collected and adapt very well to container culture and bonsai techniques). If you want an extremely "beginner friendly" species, try Carolina hornbeam. More easily collected and develops very quickly. I wouldn't waste time or space on red cedar (and I've tried it a few times with junky annoying results) UNLESS i could find one with a trunk with some interest--and it would have to be VERY interesting to justify the time and effort in digging it up.
Sow's ear doesn't do this species justice as bonsai material. A better descriptive comparison is at the other end of the pig...
