Learning To Knit

Now if you are an experienced knitter then please do not inspect my knitting efforts too closely.

My mother in law has been teaching me to knit and so far I have knocked out a dishcloth knitted out of crochet cotton and have started one with a ball of 100% cotton.
I seems a bit strange saying ball of 100% cotton as the crochet cotton is 100% cotton too so how do I specify there is a difference?  I would have said it was ? ply but there was no such measure in the packaging.

The first one I knitted out of crochet cotton turned out  funny rectangle shape but works fine and the open weave means that it dries quickly.
I have been writing this for a few days and have now finished the second one and it came out nice and square and feels lovely and soft in the hand, not a dropped stitch in sight.
Well better go and cast on for another one.
