Swatch #1: Berroco Touche
This was one of the first yarns I purchased. I originally bought a few skeins at Hill Country Weavers in Austin, and then purchased additional skeins in the same dyelot from Webs, after realizing I couldn't do much with the amount I had. I've used this once before, as the sleeves and neckline of my Two-Toned Shrug. It has excellent stitch definition, but my gauge is a bit off with the suggested needle size.
Swatch #2: Elsebeth Lavold Hempathy
I just acquired this yarn from Supercrafty, and hadn't decided on a pattern when I purchased it. I wouldn't have considered this pattern in hemp, but after seeing Blumunchie's FO, I decided it was a possibility. After starting a swatch (I didn't finish), I've ruled it out. In comparison to swatch #1, I just don't like Hempathy for this pattern. The stitch definition is not as nice as the other swatches. I'll use it for something on smaller needles.
Swatch #3: RYC Cashsoft DK
I happened to have a swatch of this (in plain stockinette) that I worked a few weeks ago for another project on the same size needles. The gauge is dead-on.
Swatch #4: Knit Picks Shine Sport
I like this one as well. The gauge is similar to the Touche.
I decided to go with the Cashsoft DK. The gauge doesn't need tweaking, which is nice, and I should just a little more yarn than I need, which is good for my yarn stash!
I'm glad I did this exercise. I learned a bit more about gauge, and I recorded my gauge for each yarn on Ravelry, so next time I'm swatching, I'll have a bit more information!
