A plain white, narrow border around this, and then onto another border :D:D:D

That center is adorable!!!

The center is adorable.

I also think the pinwheels are overwhelming to the size of the center.

I would leave the pinwheels off the sides, and add plain side borders and do some cute applique if you can.

I like it and I would continue the pinwheels and bind it in black. If you think it's too busy and the eye may need a rest, break it up with one block maybe the second one from the bottom on the right side with a zinger. Maybe a tiger block or your signature block "love from Grandma"
I like putting zingers in my quilts. It make for such interesting conversations.

I love the pinwheels on the sides...and then put the strips around that like you said...

I really like what you have done so far on the quilt it is going to be so CUTE. :-P

maybe put a border of gold all around it? It's a darling quilt.

Pinwheels in the corners, with plain blocks between and a centered pinwheel on top and sides.

That is absolutely adorable. What a clever use of a buggy and tiger. I'd do maybe a 2 1/2 inch border and then a 3 1/2 inch border to finish and bind it in the color of the 2 1/2 inch border.

I like it with the pinwheels on top and bottom only best -- maybe add a small white border to the sides to continue the row around the sides -- then add the borders how ever you like.
