Here are some snowflakes the grandkids and I have been making here, since December 1. Some of the ones we've made are in the Jacquie Lawson Advent Calendar for 2017 (https://www.jacquielawson.com/advent) and I can't share them with you. The others, we made at: http://snowflakes.barkleyus.com/. Also, there is Paper Snowflake Maker (http://rectangleworld.com/PaperSnowflake/) and Snowdays (http://snowdays.me/).
I'll share what we've done so far, below, and we'll add more throughout December.
