octo - when you get ur wool it should say on the band, but most of the aran wool i have says size 5mm needles. get whatever u can get locally as ur just learning and the tension (which is why u need diff sized needles) isnt really important. i think argos do a kids learn to kint set, which would do you all to practice ;)
when we get started on the longies you will need a particular type of wool and size of needle, but not to worry i will tell you exactly what u will need
