Bob, I couldn't agree more! I'm constantly going back to check on stitches (for some reason, I constantly have to check on how to do simple buttonhole stitch, as well as hem stitching - my mind just goes blank!)
I think that you will enjoy Asissi (from the town in Italy where it enjoyed a huge revival in the 19th century and so re-got its name. Historically, it was called Voided Work and was done in long-armed cross stitch).
The Irish stitching (Mountmellick) is also a lot of fun, and can lead you onto Schwalm and Casalguidi forms as well (which are both very similar to Mountmellick).
As for simple instructions, I am currently working on an e-book to be distributed through Bella on simple embroidery.
