So very grateful for this little thing! While I've tried to keep yarns by weight together, ummmm, sometimes they just get jumbled up. It really does work! Thank you <3 <3 <3

Love it

I am a new knitter so can't always tell the weight by looking. It worked perfectly. I bought one for a friend for Christmas. We were talking and she commented she had lots of yarn she didn't know the weight of, so hers was in the mail the next day. Not waiting for Christmas.

Oops!

I still have to come in and pick this up. Yikes!
