Did this in 1999 or 2000. The original design was a half page thing so it looked smaller than it ended up being. If I'd had any idea what I was getting into, I would have stopped or never even started. I did this one winter, and started to do the different birds in different colors because it was hard to keep track of where I was in the design. I was also curious to see if the birds actually had all their parts. After that, it was a short step to completely filling it in.
If you look very closely along the upper edge (at a higher res) you can see some hashmarks I wrote onto the fabric in purple pen to count out the perimeter.
