To assemble the quilt, all I did was add borders with corner squares. I wanted the focus to stay on the center panel and the adorable 5-year-old signatures, so I kept the piecing simple and used solids for the border. After basting, I added teacher's name and the year with fusible web. Then I appliqued with a zig-zag stitch.
I outline-quilted the border and corner squares. I also highlighted all the signatures with quilted boxes. Then I decided it needed more quilting, so I outlined some of the fun frogs, too.
I love how the outlined signatures turned out! The back really shows off the effect of the random-box quilting:
I also made a similar wall-hanging sized quilt for the teacher's aid the same way as the larger quilt. I just added hanging tabs, and did a turn-out and topstitch finish on the edges rather than binding.
