This is a real newbie question and normally I would ask mum but she has gone away
So probably looking really silly ....
To use a stitch marker do I attach it to the needle (I currently have it attached to the knitting)? The next row in the pattern says to 'slip marker'. This was my give away that maybe it was meant to be attached to the needle. If this is the case, then this mean to transfer the marker to the other needle?
If it helps here is the pattern, refer to the top of page 2. http://www.dunmani.co.uk/newflower/files/FlowerpotTotsDKShortiesAndLongies.pdf
