Sorry if these questions have been asked before, it's late and I wanted to ask rather than search the whole site

1) Fast travel - how does it work? I know it causes travel weariness for both travelling to your HF and Village and that you can always travel to your HF regardless. My question is what other factors affect fast travelling and the travel weariness percentage caused by each type (HF, cross road or Village).
I recently fast travelled back and forth from my HF and village and noted it took about 11% each time. I then went travelling a long long way only to find I could not travel to my Village, I was on 34% travel sickness. I could travel to my HF so I did that and noticed my travel sickness shot up to 96%! Is this normal?
Does anything else affect fast travel?
2) Item placement - is there any way to change the direction items face? e.g. crates you can stack up alongside the E side of a Timber house to get several crates but for straw crates you can only get a few due to their positioning, can you change this?
Many thanks!
