I can't tell you how many times we've had customers come in to the shop for help on the second front of a cardigan, or on the second side of a v-neck pullover, when their instructions have told them what to do for the fist front (or side) and then told them to simply "reverse the shaping" to complete the second side. It's very common for a pattern designer to include this in the instructions. Not only does it save precious paper space on the printed pattern, but once you've done this "reverse shaping" several times, it really isn't difficult, so I think they assume we all know how to do it.
If you don't know how to do this, and even if you DO know, Amanda from Berroco has just made an excellent video on this very topic. So take 6 minutes now and watch as she walks us through the shaping of a right front of a cardigan, and offers up some great tidbits of info along the way. (Right front? Is that as we're looking at it, or as we're wearing it? Another top question we get!)
Afterwards, be sure to bookmark it so you can refer back to it the next time you run into these nebulous instructions.
