Thought you might like those! The Amethyst Dreams is the class I've just finished teaching - though am about to start a 2nd offering. But, to the point, the threads are no wool. I did up 5 new colorways for that one (to suit my crew of canvasworkers) - and when they're done I've promised Laura to send her pix of them so she can display as she likes. I'm doing a deep purple with midnight blue/violet, another is all deep aqua with teal, another in reds & coral, one in sage/khaki & burgundy, and Donna has done hers in Black/grey & silver - it's quite elegant. The threads for alol of Laura's designs start with a Caron Watercolour, and then build from there. For this piece, it's Watercolours (which is really soft, pima cotton), Waterlilies (though some of my color sets use a Silk 'n Color), some solid silks, some Perle 5, a few weights of metallics, a tubular knit (Frosty Rays), and the hateful Hilites - which is a metallic/rayon kind of blend from Rainbow Gallery. We're also using Silk Lame - which is a braid of silk and very fine metallic. Anyhow, some of these pieces (not the gardens so much, but the geometric) are great exercises in seeing how texture affects what you see. For this one - the inner areas are all done in the lighter threads - for the most part - lots of layering - then the outer - patterns continue in the same color - but heavier thread - so it's really interesting to see that deepening effect.
Anyhow, I encourage you to play with one of those charts - if you like one. They definitely aren't your grandmother's NP. While there is tent stitching in various places on many of them, there's also a fun combo of different stitches. Just the word to the wise - there are some disconnects between charts and written instructions, and not all the stitches are diagrammed (kind of the assumption that you know how to do some of them). But, all her layered stitches are diagrammed - it's just a question of carefully looking at the chart vs the stitch diagram vs the color key - as to which threads are really supposed to be used. On the whole, the stitch placements are very clear. And not difficult to do - but, the laying tool does come out.
