This pattern is for a mosaic square that can be used in other types of projects, such as blankets, pillows, trick-or-treat bags, table mats, etc.

Any yarn or hook will work, depending on the desired size of the finished square. I used yarn weight of 4 with a 5.5 hook, which creates a square of 13.5” x 13”.

You will need 2 colors of yarn - one for the background and one for the bat. You could also use variegated yarn for the background, or use 2-3 colors of yarn to create a striped or gradient background. (The sample image actually has 3 different shades of grey, as I was using up scraps.)

For projects using 2 colors, (one for the background & one for the featured design), you will need approximately 2 oz of each color for a worsted or aran (wt 4) type of yarn.

Pattern is in US crochet terms.
