I would do the blue. Second choice would be the plaid. It's a great quilt!

Like some others, my first idea would be to use the blue from the border if you have enough left. Cute quilt!

Looks like you’ve got plenty of advice but I wanted to add what a nice quilt...the yellow for the sashing was a perfect choice.

Any color that you would use for the binding will get dirty. I would go for the yellow as it brightens up the other colors in your John Deere quilt. For a color to "pop" it needs to be in 3 places....your inner border, the tires on the tractors and I would do the binding. Let us know what you decide.

Definitely Blue!

thank you everyone for your replies and kind words. I don't believe I have enough of the blue to bind this one (I am using it to bind another quilt... but maybe I can change the plan for that quilt ha ha)

I didn't think about the plaid. I did fussy cut the tractors out so I do have that scrap to check into

I will let you know thanks again

Dirt!? What dirt?! You aren't going to let anyone get it dirty are you? LOL

I think you have your answer. It's a great quilt!

Cute quilt. I think the blue would be good for binding. I feel the yellow would distract from the blocks.

Blue would continue to frame the quilt

My thought too.
