I just started knitting back in April, so I'm slowly building my needle collection. I started off with two pair of bamboo straights for a beginning knitting class, then got a few Addi's for my next projects. I wasn't sure that I wanted to get the Denise set since I like the Addi's so much, but I couldn't resist Amy's rainbow Denise set. I love it!
I still love my Addi's, but I find it just depends on the yarn I'm using for a project, or what needles I have available that aren't already in another project I've started. Plus, I love having needle sizes 5 - 15 right there in case I need them. And it's so easy to switch needle sizes within a pattern. A baby hat I'm making right now starts out on size 6 needles, and then moves to size 8. Making the hat with the Denises sure makes the switch super easy!
So I love them both! And it sure is handy to be able to fit that Denise case right in my knitting bag. (Plus Amy sent them off to me very quickly once I'd ordered them! I was surprised how fast they arrived.) Of course I also have a few more Addi's on my wish list... :D
