Hello! I been knitting for several months now, and am doing some wool shorties (to cover cloth dipes) and while I have done this pattern before, it was with intense help from my knitting teacher. This time, the pattern has gone swimmingly (bcs I actually understand it!

) but I have run into a problem, so I am hoping someone here can give me a quick answer. The shorties are knit in the round, and I have completed the first leg, which means I had to cut the yarn after I cast off. Now I am ready to do leg #2, but cannot for the life of me remember how to start the new yarn. The beginnings of the leg are still on the original needles, I need to move them to a smaller circumfrence, so basically I need to know how to start with a cut end of yarn so I can knit onto the smaller needles. Does this make sense? Sorry it is so long!!
