The past few times I've been into my local yarn shop I've noticed and lusted after a yarn called Caracol by Malabrigo. The last time I was in, I sat down and looked at it closely - it's bubble crepe! I can make that!
I grabbed some Cjkoho BFL and sewing thread.
I spun a woolen single Z, about worsted weight.
I plied it S with the sewing thread.
I ran my yarn back through my wheel again S, doubling the ply twist.
Then plied it again with the thread Z. And presto chango, bubble crepe!
It's so easy and fun, I made a whole pile of it.
Now to knit something......
