When learning to knit a color changing yarn is a terrible idea, and needles can be larger than needed but too large and its even harder to do. A nice light or bright color of worsted and needles sizes larger than label reccomendation will do.
#Knitting/Crochet_Stitches - "This decoration for knitted projects looks like #Latvian_Knitting, but is really just crocheted slip stitches made into a knitted foundation. It's really easy to do and is a very effective way to add design interest to your knitting." Enjoy your knitting and crochet from #KnittingGuru
