I photographed each 'stage':


Once I had finished the tapestry it was fairly warped out of shape, I therefore had to 'block' my tapestry in order to straighten it out. To do this I pinned squared paper to a board and stretched the tapestry into shape, following the lines of the squared paper and pinning it into place. I then sprayed the back with water and waited for it to dry naturally before unpinning.
The next step is to make the actual bag...
