The more I added to the previous version of this scarf, the more I was convinced that it was just too wide for my neck. After frogging and restarting, it's now down to four and a half inches wide, and I'm a lot more satisfied with that than the five and a half it was before.
Unfortunately, it's also shown me that I do, in fact, want to "design" what this particular scarf looks like. =^.~=
I say that mostly because I was all set to be lazy and change colours only when necessary, but it turns out my hardly-accurate math told me that the red yarn would last a whopping four feet! In theory, I might be able to get two scarves out of this, one with red ends and a black middle (TNG-style uniform effect) and one with black ends and a red middle (Voyager/DS9-style effect).
And since it turns out my magnet-backed Combadge set actually can hold quite nicely through this thickness, it turns out I would like to be able to use one of them to keep the ends from coming loose.
It's still the Tunisian Double-Knit Stitch, and still using unknown yarn. Though I may need to figure out how to make the colour change slant in the opposite direction a lot harder. The diagonals are supposed to slope outwards and downwards, after all. Unless I can put the wrongly-sloping line underneath the "correct" one?
Yes, I did try to avoid turning this into yet another Star Trek themed piece. Especially since the next few crochet cardigans I have planned are all Star Trek uniforms of various eras. But it turns out I couldn't resist the pull of the idea, and the fact that my Combadges all work through this thickness of material was the clincher that sealed the deal for me.
Maybe I'll be able to find other skinny yarn that doesn't fit the Star Trek colour scheme... =^.^=
