This is a circular variation of the original Cosmic Coaster, and I'm very pleased with it!
This is a 6-round pattern, using 5 colors of Lion Brand Bonbons, a sports-weight yarn.
Crocheted with a 3.75 mm (F) hook, the coaster measures 4½"/11 cm across.
For those of you who use UK terminology, here are the stitch equivalents:
sc = UK dc
dc = UK tr
The first three rounds are worked in exactly the same way as the Cosmic Coaster, where I have written a full photo tutorial.
The only difference is that I have used three different colors for these first three rounds.
So if you need to see the photo tutorial for the first 3 rounds, do check out that page!
I've added photos below from the end of Round 3.
Round 1: In color A, ch 4 (counts as a stitch); 11 dc into 4th chain from hook.
(12 stitches worked.)
Join with a ss into top of 4 ch.
Tie off. I tighten the knot gently, and weave this end from front to back under the top two loops of the next stitch before weaving into the back.
Join color B into the space between any 2 stitches. I made a slip knot, then pulled the loop through to the right side of the work.
Ch 3 (counts as stitch at start of round for this pattern); dc into same space.
(2 dc into next space between stitches) 11 times.
(24 stitches worked.)
Join with a ss into top of 3 ch. Tie off.
Join color C between any two stitches that are worked together into a space - so, into the "V" shape; ch 3, 2 dc into same space.
(skip next space, 3 dc into next "V" shape) 11 times.
(36 stitches worked.)
Join with a ss into top of 3 ch. Tie off - and here is the result:
Round 4: In Round 4, a "space" means the space between each group of 3 stitches.
So - join color D into your space:
ch 3, 2 dc into same space.
(ch 2, 3 dc into next space) 11 times.
ch 2, ss into top of 3 ch.
(36 stitches worked with 2-ch spaces between them.)
Round 5: Join color E into any 2-ch space; ch 1, sc into same space:
(ch 5, sc into next 2-ch space) 11 times.
ch 5, ss into 1st sc:
Round 6: ch 3, 7 dc into same stitch you joined into; ss into 5 ch space:
(8 dc into next sc; ss into next 5-ch space) 11 times.
Here we are working around the circle:
To finish, join with a ss into top of 3 ch.
(12 groups of 8 stitches worked.)
