Difficulty:

• Finished size: Approximately 10 cm (4 in) in diameter
• Difficulty: Beginner
• Pattern language: US crochet terminology

You will need:

• Cotton yarn: multiple colors
• Hook: 3mm
• Needle: for sewing
• Optional: A thinner yarn can be used for the decorative lines between the rounds.

Abbreviations:

• ch - chain
• dc - double crochet
• inc - increase (2 dc in the same stitch)
• sl st - slip stitch
• (..) - repeat the sequence inside the parentheses
• x and number - the number of times to repeat a sequence
• [..] - the number between square brackets is the number of stitches at the end of the round

Notes:

You can use a different hook size, as well as a different number of rounds or colors. The finished coaster size should be 10cm (4 in) in diameter.

The pattern is written in US terminology.

Make two of the following:

Row 1: With the first color, make a magic circle, ch 3 (counts as first dc), then continue with another 13 dc in the magic circle. Join last dc with sl st to 3rd ch of the first dc attaching the next color. [14]

Row 2: ch 3, (2dc in the same stitch) x13, 1 dc in the same stitch as first stitch. Join last dc with sl st to 3rd ch of the first dc attaching the next color. [28]

Row 3: ch 3, (1 dc in next st, 2 dc in next st) × 13, 1 dc in the same st as the beginning ch-3. Join with sl st to the 3rd ch of beginning ch-3. Change to the next color. [42]

Row 4: ch 3, (1dc in the first stitch, 1dc in the second stitch, 2dc in the third stitch) x13, 1 dc in the same stitch as the first stitch. Join last dc with sl st to 3rd ch of the first dc attaching the next color. [56]
Attach jade color on the next stitch with a sc.

Row 5: ch 3, (1dc in the first stitch, 1dc in the second stitch, 1dc in the third stitch, 2dc in the fourth stitch) x13, 1 dc in the same stitch as the first stitch. Join last dc with sl st to 3rd ch of the first dc. [70]
Cut the yarn and weave in ends.

When you are at the last dc, cut the yarn and pull it out the last loop. Then, insert the tail on a needle. Insert the needle through the third chain of the first dc, and then insert back at the last dc, on the top “v” of the loop.

Decorative lines between the rounds:

Work slip stitches over the top of the stitches between each round. Insert the hook into the first stitch of the round, pull up the yarn, and continue around the coaster. A thinner yarn works well for this step.

Cut the yarn and pull it out the last loop. Insert needle on the yarn.

Do this for all the rounds.

If the coaster is not completely flat, you can block it. Soak the coaster in warm water, then gently squeeze out the excess water using a towel. Flatten the coaster into shape and leave it to dry overnight.

Sewing the two sides together:

Make two identical coaster circles. Place the two circles together with the right sides facing outward.

Take a piece of yarn and thread it onto the needle.

For this part, I like to use the same color as the last row made and also I like it to be a bit thinner than the yarn used when making the rounds. I believe it works ok with the same size also.

Take one piece of the coaster and insert the needle under the back loop of the first stitch (“v”).

Take the other side of the coaster and place it near the first one, having the right sides (front sides) on the exterior.

Insert needle under the back loop of the first “v”, for the other piece of the coaster.

Continue sewing through the back loop of each stitch, matching the stitches on both pieces.
