Heres a little tree i picked up a few months ago in a local garden center. It wasn’t grafted and I liked the movement in the trunk so i said i would pick it up, Heres a photo of it at the march meeting of the club. 
After a bit of discussion I wanted to do a bit of chopping with Marks nice new branch cutter. So we cut of the branches we didn’t want and sealed what we cut. Here is a photo of the tree a few weeks later repotted in the same pot but with different medium.
And here it is last week
