I love my Denises, but the new needles from Knit Picks are really tempting.
I was intrigued and a bit tempted when they came out with their mental interchangables. However, I've never been a big fan of metal (though I'm realizing, as I improve as a knitter, that I might appreciate their speed a bit more).
But, now they have wooden interchangables and they are swapable with their mental needles. And, to add to the temptation, they are colorful. I'm not sure if I'd call them "pretty," but those colors look like fun.
