special stitches from section 1 of Vire...

k2tog / Cable Right:

The above video (on YouTube here) specifically shows the k2tog/C3R1 used in section 1 of Vire - the same technique will work for any right (back) cable which starts by working a k2tog decrease. (Vire section 1 also uses k2tog/C5R1, k2tog/C2R1, and k2tog/C1R1, so for these just replace the 3 front stitches in the video with 5, 2, and 1 front stitches, working them all the same way.)

Cable Left / ssk:

The above video (on YouTube here) specifically shows the C3L1/ssk used in section 1 of Vire - the same technique will work for any left (front) cable which ends by working an ssk decrease. (Vire section 1 also uses C6L1/ssk, C2L1/ssk, and C1L1/ssk, so for these just replace the 3 front stitches in the video with 6, 2, and 1 front stitches, working them all the same way.)

special stitches from section 3 of Vire...

k2tog/C2R2-m (cable right starting with a decrease):

The above video (on YouTube here) is the k2tog/C2R2-m used in section 3a of Vire; k2tog/C2R2 in section 3b is the same but without a marker involved. The video begins with a cable needle; skip ahead to 1:54 for without a cable needle.

k2tog/C3R4-m (cable right starting with a decrease):

The above video (on YouTube here) is the k2tog/C3R4-m used in section 3a of Vire; k2tog/C3R4 in section 3b is the same but without a marker involved. The video begins with a cable needle; skip ahead to 2:22 for without a cable needle.

k2tog/C3L4-m (cable left starting with a decrease):

The above video (on YouTube here) is the k2tog/C3L4-m used in section 3a of Vire; k2tog/C3L4 in section 3b is the same but without a marker involved. Use the same technique (without a marker) for the k2tog/C2L2 in section 3b, but with 2 stitches in both front and back instead of 3 in front and 4 in back. The video begins with a cable needle; skip ahead to 1:58 for without a cable needle.
