Traditional Victorian crazy quilts were made without patterns. Basically you just sew your fancy fabrics to a muslin foundation and embroider and embellish and then put your blocks together in what ever manner suits you. A backing is added and the quilt is tied just thru the backing and the muslin foundation so you don't ruin the look of your needlework on the top.
There are a whole lot of books on crazy quilting. You can probably find a couple of used ones by searching thru Amazon. The silk ribbon emboridery books by Judith Baker Montano are excellent. Plus there are several books on just embroidery stitches.
