Ok, so I have only been working on this in my 'spare' time, but it has taken me four weeks to complete this TAST! I think this is something of a break through for me. Gone are the neat lines of carefully planned stitches. Although I had a vague idea of how I wanted this to look, I have really felt my way and let the needle guide me and I feel somewhat liberated by it.
I began with a piece of muslin and made running stitches across it lengthwise with DMC Perle cotton. I then gathered the muslin to fit a pre-marked area on felt. Using the 'tails' from the gathering threads, I attached the muslin to the felt using French Knots. I then spread or bunched the gathers in a random manner and began filling the flat areas with French Knots.
I kept selecting threads and adding knots where it felt right and kept going until it felt finished.
