I found two types of baby yarn at Hobby Lobby that had a thread of rayon in them. I bought a skein of each to make some swatches to try and replicate that shawl that my Mom's friend was wearing at her wedding. They knit up quickly and then I blocked them.
The shimmer shows up better in this yarn and I like the way the horseshoes look in it, but the yarn feels rather crunchy in addition to being a pain to knit with.
This one feels much softer to the touch, knits easier, but the shimmer is almost un-noticable. So far, this is my preference. Now if I could just find a nice slightly ivory wool yarn with the rayon thread in it. The pattern needs a bit of tweaking to match the one in the photo, but I think I know just what to do now that I'm familiar with the pattern! That will be the next swatch!
I did go hunting through my stash and found this cotton and silk yarn that my mother used to weave with. I thought I'd give it a try, but even without blocking, I can tell that it's just too uneven for a pattern like this. Need to find something else to do with this one though!
Blessings and peace to all!
