Linden crotches can have some very unique patterns. Also, if you want some straight colored dyed pens, this is also a very consistant wood to work with.
Try using some branch wood down near the joint, and you might get some real nice grain and even some color suprises.
Left in the sun, and too much air, though causes it to turn a real ugly yellow, and yellow is my favorite color
If you are able to get some larger chunks of this wood, it is a highly prized wood for carvers. It is worth some money. The carvers typically do not want any wood with some indication of figure ini it though, because then it looses its carvability consistancy in those areas.
It has no real value as firewood though, because it burns way too fast.
A guy the next town up from me used some, and complained that he kept warmer by his actions stoking the stove than by the actual heat put out by the stove (what a waste of wood and money)
