Tartan faults

[Dutch piper]

I just received fabric in the "whisky tartan" for making a kilt.
The selvedge is a bit crooked in my opinion. I'm thinking of hemming this kilt.



Also, the fabric has been skewed a lot on the roll. As you can see in the picture.
Is there a good way to straighten out the fabric?


Any advice is welcome
