guarantee it will barely change, I used to work ages ago in a yarn place and like 1roll of yarn-that could make 100's of scarfs-or like 50tshirts was only £6.99 and company's sell stuff off for big prices due to the logo/label, but if going for more plain stuff or not really named then it's going to less, also bare in mind one of the biggest part of how GB was built up on was mills full of sewing machines etc.
