I have done it!!!
On 17th June 2011 I bought the Farmer's Wife Sampler Quilt book from Amazon. On 30th May 2012 I finished the one-hundred-and-eleventh and final block. Here are the blocks I made in that final sprint for the finish line (when I picked the fabric for these last few blocks, Michael said I should avoid orange - he'll be pleased how seriously I took his advice!):
#99 W.C.T.U: I really wasn't sure about this block. I was very tempted to swap it out for something easier, but I was worried I would regret it later. Also, it would have been the thirteenth block I'd swapped. I don't believe in that kind of thing, but it convinced to plough ahead. I did, however, avoid the stripe in the middle. And I'm really pleased with how it turned out (so much for no orange).
