Here's my obligatory Holiday contribution, candy cane nails (on a practice board)!
White: OPI's Alpine Snow
Red: CM Nail Art's red
Silver: stripping tape from Transdesign.com
Do you white base first, then freehand the red stripes (you could use tape to delineate the edges, but that'll cost some time), then add a strip of tape to each red edge. Seal it with a top coat or two. Easy as pie!
