That didn't work. I had some bright red boucle yarn that I was planning to use for the last ring of big hearts. I finished off the Noro shown in the last article, and started with the boucle. Made it to two rows and gave up. Forgot to take a picture; sorry.
The yarn was too thick for the lace--couldn't see the stitches, couldn't see the pattern developing, and worst of all, I couldn't see what stitch I was on--whether I had already done the two K2T (effectively), or only one. Unpleasant.
So I unpicked, and that messed up the Noro rows, so I took them down too.
I slipped into Great Yarns before class last week and found some bright red mohair, as well as a skein of Rowan's Kidsilk Haze in a darker red, both on sale. That counts as "knitting from stash," right? The Rowan has tiny sequins, and Pulse needs sequins.
Here's a close-up view of shading the Noro (with a thin strand of pink laceweight alpaca) into the mohair, in alternate rows. The pink flashes are the last of the Noro.
The dull yellow right after the navy is a shortish strand of orange mohair; didn't have much of that at all. Then I started with the more orange end of a small winding of Noro sock yarn, which shows as the yell to peach in the picture. The brighter pink is the alpaca.
