Because stained glass designs had a working use in a studio, they were stored rolled up and were frequently unrolled for use; this means that they are very often dirty and tatty at the edges. In the early years of this century, after Burne-Jones and Morris's deaths, a number of designs were sold off by the firm, and for this were hastily put into frames. Four of the Whitworth's stained glass designs retain these frames, which are of a dark wood and have a flat moulding; they are the only frames in which the drawings have ever been.
