Good eye checkup. Back to suggestions....
4. How about a project for digitizing embroidery designs for quilting in the hoop? It could include the best type of underlays for this technique and the best type of embroidery stitches (density, length of stitch, etc.) for embroidering on two layers of fabric, batting and stabilizer. Options: This project could have tips for best type of stabilizers to use, tips for how to hoop all these layers of material, and tips for how to manage quilting in the hoop on a home embroidery machine. I found books on how to quilt in the hoop for very small projects, but absolutely no information out there on how to manage quilting in the hoop on a large quilt.
(Aside: I used one of Diane Gaudynski's feathered wreath designs for quilting in the hoop. I was in a hurry and I thought it would be quicker to do all those feathered wreaths in the hoop than to free-motion quilt them myself. (My free-motion feathers and wreaths leave a LOT to be desired.) Quilting them in the hoop was not necessarily quicker than free-motion quilting feathered wreaths myself. But each quilted feathered wreath stitched out perfectly. I used an OESD washaway stabilizer. It worked beautifully.)
5. Also, I suggest you include something on digitizing for endless embroidery (like you would do to embroider a border). I think there are stitches you can add that you can match up when you rehoop to make the rehooped embroideries line up perfectly. Hope this makes sense. A lesson on this would be great.
6. Finally, I suggest having someone test your instructions by actually doing them. Ideally, this would be someone who has used V7 enough to be familiar with the basics, but who is not a V7 expert. When I wrote procedures at work, I got someone who didn't know how to do the task to try to follow my written procedures. If that person could follow them without any problems, I knew the other staff members could.
Best wishes with your book.
