I did a crazy quilt last year (sorry no pic). Muslin was used as for a base and I used all the fancy stitches from my Viking SE to embellish the top. The back was sewn to top with right sides together sewing all around edges, leaving space to turn right side out and stitched closed. No tacking/tying. It was one of my favorite quilts to make, because I was more focused on creativity and less on matching seams up. Loved it.
