At one time I took a night school welding course. We wefre given a very interesting exercise byt the instructor. This was O/A but could be done with TIG just as well. The purpose of the exercise was to practice puddle control while getting good fusion.
Start off with a piece of (say) 1/8" thick mild steel about 3" square. Make a puddle in the middle. Now start to build up the puddle into a rod. When it gets to be a few inches long, branch out into two directions. Build them up for a few inches then branch. Make a steel antler.
When we were satisfied with our "piece", the instructor came along and dropped it on the floor. If it broke, you needed more practice on getting good fusion. Mine didn't break so I drilled two holes in the base and gave it to my daughter. We fastened it to the inside of her closet door as a necklace hanger.
