I have a bruise on my thumb from sewing in the liner. I decided after making a bag for my sister Claudia and myself that just sewing in with regular thread wasn't working. The thread would break apart after anything was placed in the bag. The knitting gives, but the fabric doesn't, as you can see not a match made in heaven. So now I am sewing the liner in with elastic beading thread. It seems to work much better but is much harder to sew with.
