My first thought was stipple, but this would also work with all over interlocking squares of different sizes. I saw it on a blog, and it was very striking.

Love it! Love it! I just adore bright colored quilts.

absolutely gorgeous! love all the fabrics. you'll have to go with the experts on the quilting as that is so not me. just love your quilt top.

You could do a quarter inch on all the blocks. Have fun. Looks great.

Thanks for the suggestions. The backing is fairly muted, using a sheet with a sunset and ocean scape. I plan on giving it to my SIL, who is a Hawaiian native and granola bar. She was ready to take it months ago, in fact if I gave it to her without quilting, batting or backing, she''d be just fine with that.
;)

Would a Hawaiian type design, the size of the block, that is quilted over each block work?

Meander would look great

Meandering will be fine! Great reuse of fabric!

I'm going to be different too :) I'm also thinking about the back since the back is plain.

The center squares has a design .. outline it with stipple meander. In the row of squares immediately surrounding the center put a vine or something. The outer squares you can SID.

How about a simple stitch in the ditch.
