Designer Notes on Errata:

I would like to report errata for this pattern. This is also available in PDF form via the errata link above.

Page 216, after working Dec Row 2 D (RS). You have the 113 stitches, the next instruction is the following: Work even for 6 working rows. rep Dec row 1 C and D—107 sts rem. Work even for 6 working rows. rep from twice—79 sts rem. Work even for 6 working rows. Mark st columns 39, 45 and 55.

It should read:
Work even for 6 working rows. rep Dec row 1 C
and D—107 sts rem. Work even for 6 working rows. Work Dec Row 2 C and D.
rep from twice—79 sts rem. Work even for 6 working rows. Mark st columns 39, 45 and 55.

Then the following instructions read:

Dec Row 3 c (RS): work to 2 sts before first marked column, dec2r, yf sl1, dec2l, work to 2 sts before next marked column, dec2r, work to 1 st before next marked column, dec2l, work to 2 sts before next marked column, dec2r twice, yf sl1, dec2l, work to end—72 sts rem.

I forgot one yfsl1 so it should read:
Dec Row 3 c (RS): work to 2 sts before first marked
column, dec2r, yf sl1, dec2l, work to 2 sts before next
marked column, dec2r, work to 1 st before next marked
column, yfsl1, dec2l, work to 2 sts before next marked column, dec2r twice, yf sl1, dec2l, work to end—72 sts rem.
