These are the final 3 of Mary's Snowflakes that will appear on this topic.
Being more traditional, from an applique perspective, I would iron the snowflake design onto the fabric that I would want to applique to a background fabric. Then I would mark around the snowflake, then cut within 1/8 inch of the design (batiks would be best to use). This would be basted to the background fabric, then needle turned. Alternately, one could also iron Lite Steam-a-Seam to the back of the snowflake to applique, press it to the background fabric and machine applique around the design after trimming the snowflake design to the marking line.
