I personally do not find the form pleasing to the eye , but you have achieved a great finish on that piece and monkey puzzle end grain is a difficult wood to do that on so well done ! I find that it soaks up a lot finishing oil as well ! Your comment on the positioning of the knots is quite true , I find they look best when on roughly the widest point of a hollow form of classic shape which typically will be about 1/3 of the way from top or bottom ( depending on shape ) . Monkey puzzle is not readily available from suppliers ,so you never know when it might be available ,but when it does there is usually loads of it !, sticky horrible resin when fresh though . ...Terry...
