Well I have completed my first gusset ever! Woo hoo! I had been avoiding glove patterns that had thumbs because I was intimidated by them, but i found a free pattern for manos silk blend yarn, so I gave it a try. It's beautiful yarn. The gusset felt a bit awkward with the M1L and M1R, but I referred to some helpful youtube videos to help me along (it's always easier once you see someone else doing it. written instructions are often confusing), and it all worked out.
