This is one of the series quilt patterns published in many 1930s newspapers under the pseudonym “Nancy Page” by Florence La Ganke. The fictional Nancy would meet with her quilt club on successive Tuesdays, where she would introduce the next block and make suggestions for fabrics, colors, and techniques. You can read more about Florence La Ganke here, and see a photo of a completed snowflake quilt here.
Nancy Page quilts tend to be either appliqued or embroidered — the Snowflake Quilt is embroidered in white on a “soft blue” fabric using several different stitches. I think this would be a great pattern for someone wanting to try out some new stitches; the project would also travel well since the designs are all one color. The entire pattern is available in my sidebar under Download Links.
