I have Nancy J Martin's Time Crunch Quilts which aim to get a quilt made and quilted very quickly depending on if you hand or machine quilt. But the whole point of this is the time spent in planning and preparation.
Having looked at Quilt in a day books the same principle applies and you have to have all the cutting done and labelled so that you can chain stitch and literally have a production line.
Seems too much like a bother and I like the easy, lazy life! :lol:
