This probably isn't a really technical question, but can anybody tell me why all the patterns I read specifically say to
break the yarn when you're at a point to be finished with the product and weave in ends (as opposed to
cutting the yarn)? Does breaking the yarn make a difference somehow to cutting it?
Also, I lost
ANOTHER knitting needle somewhere in the house, and I'm
LIVID!!!!!!!

This is the second needle I lost (the first one was a straight--the first pair of knitting needles I bought for myself--and the second is a set of circulars; both are bamboo...is there a pattern here???) Does anybody else lose needles, or is it just me?

I'm so bummed--I needed that circular to finish my hat, and now I can't!

I feel like I'm losing my mind! I've looked everywhere I can think of, but no luck.
