You could use white, Coats Glow in dark, or invisible thread, and straight stitch the six points of the flakes around the border and some small swirls like flurries (not compact) around flakes and deer in the border. Do the same for medium flakes and smaller stars on top and bottom with some swirls around deer. Outline inside and out of white border and deer(maybe do a couple wavy lines, or a quick something, inside (swirl, snowflake, pebbles) and you are done. If you get too creative inside the deer area, I think you might loose the snowflake effect. It is so cute the way it is. The whole quilt seems to twinkle!
