The red version was knit using Frog Tree Merino Worsted and the green version was knit using Lamb’s Pride Worsted.

It’s important to choose a yarn that you can block--100% wool works best, but other animal fibers/blends will also work. 100% acrylic is not recommended.

EDIT: If you don’t like the “flair” that happens on the button band end, you could try going down a needle size or two for that section. This might require slightly smaller buttons, though. Just a thought :)
