The main point was to try couched/laid threads, as in the Bayeux Embroidery. At around this time I read Heraldry for Embroiderers by Vicky Lugg, and was smitten by the heraldic lions. I made a lion...and it came out rather unsatisfactory (bad edges).
It is on (14 count?) cotton,and I decided the cloth didn't look very appealing at all, and I should embroider all over it. Problem one: using leftover weaving linen. Bad idea because 1) you have lots and lots of short lengths (and since this was before I knew about starting/ending threads with no knots...lots and lots of knots) and 2) it quickly wears to the point of fuzzy catastrophic failure. Problem two: huge difference in density between lion and background. (And I didn't remember that when I made the "white pods" embroidery!)
Anyway, I plugged away at it for intervals, but it has been dormant now several years, practically done. I gave up on a few things I wanted to do - it has enough issues that there was no way to "fix" it, and so many knots that it would have been impossible (I really wanted claws).
Oh - and to fix the bad outline around the lion, I twisted two colors of embroidery thread into cords, and couched them down.
Also done, shades of white/stitch variation sampler. Some of the effects only show if you are at an extreme angle (picture two). My hands-down favorite is the diagonal satin stitch. My hands-down unfavorites are left as examples of what not to do.
I suppose eventually I will lose track, but today is eight weeks without kitty.
