ask @Burdekin he managed to get a sewing machine
then we heard nothing much since then so I think its time we found out how they went on with there sewing![]()
Thanks how do I check Bias?
I did wonder about buying an industrial machine then selling it once the jobs done, but as you say its a mine field
