WOW!!! those alphabet blocks look awsome!!!
but, how blast resistant are they? would they survive a creeper attack?
the lapis tools are quite interesting too, concidering it is quite a waste to use such a rare thing on colouring wool... although coloured wool is nice, it needed a better use.
can i please suggest making ranging armour (please consider)
it is leather, with some iron replacing some parts, something like this...
  
  
(where the orange is leather)
this armour would be, of course, leather with some iron plates on it,
and would reduce damage taken by arrows, but have the same general protection as leather, to balance it out.
if you do like this idea, maybe also an iron bar could be crafted into iron studs, which could be added to
armour by putting them next to each other in a crafting table? this would yet again decrese damage from arrows.
i know it is alot to make, with two new armour sets included, but yea...
thanks for reading this post, even if you decide its not a good idea!
Oh yeah, I'm not sure if it is really blast resistant. the material set for it is "cloth" so it's probably not going to shield you from a nuke.
