Inspiration behind this granny square coaster pattern.
My niece loves granny squares about as much as I do. She nabbed one a while back and decided it was hers. It’s been everything; a lovey, face towel, duster, table clothe, cup cover, teether and best of all, a coaster.

She’s had it for a while now and it’s starting to come apart. I thought it was about time for her to have a new one and that’s where this pattern comes in. But before we get to it, some FAQs on coasters.
How do you make a granny square coaster?
You can pretty much use any granny square pattern there is to make a coaster, however, I decided to use my solid granny square pattern. This pattern is also a part of my 100 day project. You can read more about it on my 100 days of granny Square Projects post or follow along on Instagram.
What is the best yarn for coasters?
Cotton yarn is the best type of yarn to use for crochet coasters. You really can’t go wrong with it! i’m talking durable, heat-resistant, easy to wash, and absorbent. On the other hand, some cotton yarn can be tough on the hands so watch out for that and take breaks and moisturize those lovely maker hands please.
How much yarn do I need to make a crochet coaster?
It depends on the pattern you’re using. I personally find the best size for coasters rangers between 3-5 inches. That comes to between 12-15 yards of yarn per coaster. However, this all depends on the coaster pattern you’re working on. For this particular pattern, I used about 13 yards per coaster.

Instructions
Using your 6.5 mm crochet hook and t shirt yarn, make 2 rounds of the solid granny square. For the second round, join with a sl st in the 3rd ch of the back loop of the beginning ch 3

From here, you will work in back loops of the stitches from the previous round.

Rnd 3: In blo, sl st in each st across.

Fasten off and weave in your ends using the triple tuck method.

You can stop right here as you already have a pretty little square crochet coaster or you can keep going and add a simple beaded fringe. To do that, cut 4 strips of 7 inch t shirt yarn. Identify the corner stitch. This is the second chain of the corner chain 3. Insert your hook through the back loop of this stitch.

Pull up one strip. Using your darning needle, thread both ends of the yarn and insert your bead. Tie a knot to hold the bead in place.

Repeat the step above for the remaining three corners.

And there you have it, a finished coaster! Your coasters might curve inwards a bit (kind of like a bowl). That’s normal, especially if you worked your sl st border a too tightly. You can gently massage and pull the stitches into place to square it off more or you can also block the coasters, which will give it a nice shape.
