Pattern has instructions for a lace and ruffle pullover and bolero-style cardigan with wrist ruffles.

You will need circular needles in both sizes. I would guess short circulars in the smaller size and longer circulars in the larger size needle.

You will need 3(3, 3, 4, 4) buttons for the cardigan.
