What a lovely set to create a winter atmosphere to the coffee table. It also makes a lovely gift set. To make this set, you can use bulky weight cotton yarn and a 6.5 mm crochet hook.
You can find the free crochet pattern of the Winter Wonderland Coaster and Trivet on the website of Hooks, Books & Wunderlust. You will have to scroll down on the page to find the free version.
