I have finally completed the other side of the Mystere sweater:
I have already made a mod to the sleeves. The way the pattern is currently written has the panel in the middle with no cable pattern. I decided to add the cable pattern back into it so that it echos the panel that is on the main body. On the main body, the pattern calls for you to K7, do the cable, K7. On the sleeves, I have done K4, do the cable, K4. Other than that, so far I'm doing the pattern as written.
