The latest strip:
I’ve been alternating red patterned panels and lines of black lettering. I’ve run out of lettering, but I’m keeping the red-black-red alternation. This one is also from the V&A 14.931 sampler. I’m working the foreground double running stitch using a single thread of DMC 310 black, and the background in long armed cross stitch using two strands.
I’m having way too much fun with these patterns to stop. I’ve been talking about a sequel to TNCM for years, but now I’m engaged in doing it. I’ll be resuming my search for a decent charting program (or general purpose graphics program) specific to the needs of legible presentation for double running stitch. And given my horrible experience with the publisher of The New Carolingian Modelbook, I’m looking into other options, in specific – the feasibility of self-publishing, but I know very little about the various web-based micropublishing alternatives, but I’m open to all concepts. I do know that for this type of book paper copies are still valued by most. I don’t believe that there’s a critical mass of stitchers out there yet who would make use of an ebook stitch reference when hard copy sits so quietly in one’s workbasket without consuming batteries.
I’m also considering different formats. The last book was a 200+ page compendium of patterns, with lots of appendices of various sorts. I don’t think that’s necessary this time out. Other options exist. Shorter booklets or broadside sheets for example lend themselves more easily to web-based publishing both for the issuer and the downloader. Pricing is also problematic. The income stream this would represent is quite small, and the burden of record keeping as a small business for taxes is immense by comparison to any possible profit (discounting entirely the major effort involved in creating the work itself).
So I put these question to the few folk who visit this place and who I presume might be interested in such a thing:
1. Would you be interested in a sequel to TNCM?
2. Would you find ebook format (meaning to be read on a book reader or iPad) useful?
3. Would you be open to receiving a print-your-own PDF rather than bound paper?
4. What length book would you consider worthwhile – a leaflet of 20 pages or fewer? A booklet of 21-50 pages? A small book of 50-100 pages? 100+? (Bearing in mind that content for a 100+ page book would take a while to compile).
5. Any suggestions for publishing options aside from self-created PDF download via wiseNeedle, or commercial services like Lulu, iUniverse, or Etsy? Any cautions on the commercial service route?
6. Would you object to a higher proportion of original and adapted patterns mixed in with exact stitch recreations, so long as all patterns were documented as to origin and modifications (if any)?
7. Anything else you want to see in a book of patterns of this type?
String-Or-Nothing 
I have your first book, love it, and would be interested in a sequel. I’ve looked at ebook readers, but don’t see many textile history and craft books available for ebook readers yet, so no hurry to buy one. I adapt historic needlework patterns for use in drawloom weaving, and would prefer a .pdf download or a paper book, so that I can enter the charts in a weaving design program. As for length, it depends on how much material you have, and how much time you have available to devote to this project. I am more interested in originals than adapted patterns, since I will have to adapt patterns to fit the size of the project and the kind of textiles I make in any case.
