DAY 21 of the December 2021 LOVE AND JOY BLANKET CAL hosted by bearrye and knottiehooks.
Could be made as a standalone as a coaster

From Bearrye’s blog page:
Every day for the month of December you can come to this page to grab a free PDF pattern for an 8×8 inch blanket square. Each pattern will be free for 24 hours only, after their feature day each pattern will be available at the price decided at the individual designer’s discretion. If you do not have time to ‘Hop the blogs’ each day you can purchase our PDF bundle at any time for access to all of the previous day’s patterns and access to each following pattern at pattern release. There is no early access as this helps keep the mystery of the CAL alive!
