I made this for my friend who lost her dog last year. The great people at Pilusion made sure the custom photo mockup was what I wanted, and were willing to go back and forth with me a few times until it was just right. It probably took around 6 hours to complete, I think I did it in six sessions spread out over a couple of weeks. It took a few blocks of numbers before I got the hang of it. This might sound obvious but it happened to me and I thought I was being careful, so be very careful to make sure the string is only around one nail at a time. I had to undo all of it after around 300 steps when I realized I had accidentally allowed the string around three nails at a time. I thought the progress pics were really cool!
