Worsted is the weight or thickness of the yarn... 4 OZ is the weight of the skein. The only problem with this is if you don't use the yarn they mention, you may have slightly different yardage. If yours has more yardage, you're good. It should be close, at least, though... all the yarn thicknesses are pretty close to standard.
Hi and welcome. Have you checked out our video section? There's lots on how to cast on, knit, purl, increase, decrease and cast off/bind off. The Tips page has a video called Demo of a Small project that shows how to put the different parts together, and also some on how to fix mistakes, basic stitch patterns and other useful information.
Look at the Free Videos on the link at the top of the page. That should get you going. The Tips page has one called Demo of a small project that shows how to put the different techniques together (casting on, knitting, purling, casting off) to make an item. Just practice with those things for a while.
Hello. My name is Kendra. I found this forum while googling for knitting tutorials. I'm 39 (next month) and all of a sudden knitting has peaked my interest. I don't have any materials yet (yarn or needles), so, I've gotta get some basic supplies going before I can actually start and practice.
