Ok I don't do mine left and right. I do it front and back.
I cast on, all one needle. I split it (slip half the stitches onto needle 2). then I lay it on the table. I make sure all the bumpy part of the stitch is facing toward each other. The yarn is on the back needle on the right hand side (needle 2 in this example). I move all my stitches on needle 1 toward the right hand tip......because those are the stitches I will be knitting.
Take needle one - use the other tip....slide it through the first stitch on needle one (which would be the first stitch you cast on)...then wrap the yarn from needle two and pull through. I normally pull the yarn and the tail for the first stitch. Then let needle two just dangle.
Be careful with the first row because you can get twisted easily and there is no recovery.
Its not a stupid question. Its a little confusing the first few times. Hope this helps, and hope you get other more knowledgeable tips!
