Transferring chance card drawing into textiles work

This is a photograph of a mushroom that I have found in Withworth Park, I have taken this as my inspiration and starting point.

This is a photograph of my samplings, I have picked out one of the chance cards: draw with 20 lines. I have first drew a mushroom, then adding my own instruction to, which was: draw with 20 lines, after that use a rubber to rub out the drawing and repeat as many times as needed. Therefore, the drawing would ended up with rubbed out lines as well as the new ones. 

Then I have transformed that into textile work, first I have studied the colour of the mushroom and decided to use a rather light weighted fabric to represent that, however, I have later on added threads onto it ,but leaving the middle empty, because in the picture above, all the lines based around and leaving the middle part empty.
