maybe do flange binding use yellow and the other color

Yep, I agree with using the blue to keep focus on the center. Nice quilt!

My first choice would be the plaid and then the blue!

I hope you don't mind, I would like to use your fun tractor quilt as an idea for a little boy at church! He is about 5 months younger than my 4 year old granddaughter, and he LOVES tractors. Not barns, chickens or cows, but Tractors! Your quilt is perfect. Personally, I will probably use the plaid for binding, just because it carries all the colors in the top! I imagine I'd better make it sturdy, I think he will use it until college!

I vote for the blue plaid, but I would audition it with a tiny yellow flange in the boarder too.

Your quilt is very nice. Good looking, and I would go with blue or green but not yellow.

I like the blue. I think anything else would pull attention away from the main body of the quilt.

I would choose yellow, for precisely the same reasons as the other lone yellow chooser :).

My first choice would be the blue - but you said you don't have enough to use it for the binding.

(What was it, by the way?I have a VIP blender that looks similar to that)

I think I would avoid using the yellow - not because it would get grubby looking sooner than a darker color, but because it would detract from the center.

I would use either the same as the borders or the John Deer.
