I am a HUGE fan of these patterns, they are well written and I haven't found any errors in the ones I have used. Easy to modify as well. If you hate seams, as I do, and want to be able to try the sweater on as you go, you can't go wrong.
This is knitting up light and airy = cool cardigan just right for cool summer mornings/evenings! Easy to modify as are all Knitting Pure & Simple patterns - I am making the sleeves 3/4 length and a little longer in the body with some waist shaping as well!
