Thanks so much for the compliments. I found the panel with 8 tractors on it in a booth at the AQS show in Rosemont a couple years ago. I am a farmers daughter and had to have it. I just cut them apart and added the sashing around each block and went from there. It was very easy but I am happy with how it turned out.
I think the panel has been discontinued. It was printed a couple years ago. Clothworks put it out and there is a pattern on their website using only 4 of the tractors on one quilt. I used all 8 on the panel.
