Switching Yarn and Needles

I've been thinking I should just go get the right size circular needles for the tammy and start over because it's too much work to make a hat just for practice. That, and one of the cables on the cheapo needles I had broke yesterday. I just hope Joann's has the right size today. I may switch the yarn as well. I don't like how the Caron yarn keeps coming un-plied. I think I will switch to Woolease instead and it's on sale today 2 for $5.00 and I already have 4 skeins of it. This hat takes 8 colors, and I only have 3, so I'll need to pick 5 more colors.  There goes the ole budget. Yarn is never wasted though.
