Everything's okay apart from the bowstrings part. It's faster to bank the flax and spin it at barb like you described in your own guide.

I agree with the bowstring part.  Personal preference I guess.

Another note is the vials of water, the bank and shopkeeper are in the same hut in barbarian village and the water pump is closer as well so that is another option.

Overall great guide and I like the simplicity and the layout a lot!  Good job!
