I think of crochet in terms of the big picture, so I write patterns that way.
But, I hope this helps someone who wants to make a spiral.
This makes the smaller of the 2 spirals.
Rd 1: With the first color, make a Magic Circle, ch2, sc, dc, then use a stitch marker. Add in the next color with a ch2, sc, dc, stitch marker. (Repeat for next 2 colors).
Rd 2: Continuing on top of the adjacent colors, going in a circle as if you were crocheting in the round: 2dc in each of the next 2 stitches, use stitch marker. (Repeat for next 3 colors). (16 stitches)
Rd 3: 1dc, 2dc, 1dc, 2dc (Repeat for next 3 colors).
Rd 4: 1dc, 1dc, 2dc, 1dc, 1dc, 2dc (Repeat for next 3 colors).
Rd 5: Ch2, (dc, hdc) in next stitch, sc, sc, fasten off (Repeat for next 3 colors).
Border: I just put a sc in each stitch around, except on the corners I did (2sc,ch2,2sc).
I will be happy to answer any questions. I don't have any "in-progress" shots, though.
(To make the larger one, I just went one more round, doing 1dc, 1dc, 1dc, 2dc, etc. Then adding all 4 colors to the border.)
Thanks for looking!
