• 3 mm crochet hook

• Yarn I used milky yarn but.The yarn I used is not essential, and each country uses different standards, so I won’t specifically designate a brand. You can choose and use the yarns you want, and for crochet hooks, you can choose the right number for yarn. However, the size of the finished product may vary depending
  on the selected material and the maker’s skills. If you make it with a yarn and a needle of the same size as below, The size of the finished product is approximately 12 mm wide / 15 mm long. Thickness of the yarn used: 2-2.5 mm. Used Crochet Hook Lake: 3mm If a smaller crochet hook (2.2 mm) is used, a smaller coaster is made. I used a 3mm needle for a tea coaster and 2.2mm for a decorative coaster.
