I just did some snowflakes on a border for a Round Robin quilt I was doing for someone else. I took snowflake images, enlarged them, traced them onto fusible, fused the fabric, cut out, then fused to the fabric I used as a base. Then I machine-stitched on some of them, left some not stitched down, as my friend may have other ideas she wants to do to complete.
It was easy, but I didn't take any pictures. Sorry. I won't see a photo of the finished quilt for a few weeks (we're nearly done with our RR).
Edited to add: why not try Google? Put "pieced snowflake quilt pattern" into your search engine of choice and see what comes up?
