To quill the snowflakes I took cues from the printed ones and used a mix of plain white quilling paper and silver holofoil-edged white strips from J.J. Quilling Design in England. They're imported to the U.S. by Whimsiquills.
The edged white paper has a bluish cast that's quite nice as an accent against the plain strips. It makes me think of the sky reflecting on freshly fallen snow on a sunny day.
From the side, you can see the slight tint, but from straight-on the coils look either silver or multi-colored depending on the light and angle. Tricky to photgraph, but it's a fun paper to work with and I'm glad I had this opportunity to try it out.
