I-Spy Quilt Project: Part 3

Part 3 of my quilt project has been a long time coming. I've gotten the quilts mostly done. Since Part 2 I have added the solid border around the quilt front, pieced together the quilt backings, and attached the back, batting, and front together. I'll break this down into sections....
The Solid Border: I cut 4" strips of fabric and sewed them together into one very very long strip. Then I just added it to the quilt. I used a mottled solid to balance out all the happy colors of the quilts. Purple for Ray's quilt and blue for Ali's quilt.
The Backing: I'll post better pics of the backing as soon as I can. The photos below are just small sections of the backings. I used 3 different fabrics for each of the backs. I wanted to backs to be just as pretty as the front. So... a very large patchwork... Below is my sketch of the backing so you can get an idea of what it looks like.
Putting It Together: So after the fronts and backs were done it was time to assemble the quilts. Now, I had originally intended to lay everything out, pin it all up, quilt it, and then bind the edges. But, time was an issue and I decided to go the "quick" route. I pinned the fronts and backs right sides together and then the batting on top of that. I sewed along the edge and left a large section open. Then I turned it all around. I then had sewed up the opening and began to quilt.

The Quilting: There are so many ways to quilt. I didn't want to tie the quilt, but I also don't have the time to do to much detail quilting. So I quilted along the edge and the along the inside ditch of the outside border. Then I did a large checkerboard inside the I-Spy part. For the middle border where all the large squares are I'm doing some free-motion squigly quilting. I'll get close ups of the quilting and finished photos for Part 4.
