As the winter wore on, James begged for another pair of what have become known as carpet trousers - winter-weight baggies. These ones are not cotton, but wool, quite thick with a very coarse weave. Like the thick cotton baggies, I finished the edges of the fabric first, to stop it all unravelling. The fabric caused the thread to wear thin and snap periodically. I am not sure why this was - but guess that parts of the thick weave are very dense.
