I love KERSTI and in my book it bakes the best MUFFIN hat ... a lovely baby gift and one that should be in every knitters repertoire ... one skein = one hat ... done and dusted! Take a peek here how lovely they are! http://www.tantesophie.com/blog/?offset=1386613336511
I love the little short circulars for making sleeves ... they are a bit tight if you have big hands which I do not and a bit fiddly when binding off I switch to a second needle for that ... other than that ... I have them in all the sizes up to a 5mm I think ... they beat double pointed needles for sleeves anytime.
