So you buy a length of fabric online. An enormous parcel arrives. You wrestle the contents into the washing machine, and hope the weight doesn’t overload it. The washed fabric takes over half a room while it dries, carefully arranged so as not to pull off grain. You get your pattern, cut out the pieces. The fabric is gone and all that’s left are some scraps and a tiny pile of cut pattern pieces a fraction of the size of what you started with. It can’t possibly be enough to cover a body. And yet it all works out in the end. It is a mystery.
