3 Color Spiral Motif
Form an adjustable ring by looping the end of A behind itself putting the yarn tail behind the working yarn (the yarn coming from the skein); hold the end against the loop and insert the hook in the center of the ring. Work stitches over both strands of yarn.
Round 1: With A, CH 1, (SC, HDC, DC) in ring, remove hook from loop (pull loop long so stitches don't unravel); join B to ring and CH 1, (SC, 2 HDC) in ring, remove hook from loop; join C to ring and CH 1, 3 SC in ring, place marker in last stitch to mark the end of the round (9 stitches). Do not remove your hook from C. Pull the yarn tail to tighten the ring.
Round 2: Continuing with C, [2 SC in next stitch] 3 times, remove hook from loop and reinsert in loop of A; with A, [2 DC in next stitch] 3 times, remove hook from loop and reinsert in loop of B; with B, [2 HDC in next stitch] 3 times (18 stitches). Note that a pattern has been set up: You will always work C into A, A into B, and B into C. It is very useful to mark the last stitch of the round, because the end is actually in the middle of a section of a particular color.
Round 3: Continue as above using DC - with 1 or 2 DC in each stitch as needed to keep piece lying flat. Continue until desired size. To finish each color, do 2 HDC, 2 SC and slip last stitch.
