In most of lace knitting, the WS is called the "resting row"...and is always just Purled across.
The RS is called the "working row" ...and that is where all the intricacies are worked!
(This principle applies to a lot of cabling patterns, too.)
I love the "resting rows"! This is the row where I make double sure that all stitches are accounted for...a "head count" if you will.
In lace, the errors are usually in the "yarn overs". Either one too many, or I just plain forget a yarn over, or two or three! Better to catch my error before knitting my resting row. Within the resting row, you can create a YO when you get to the missing YO...and if there is an extra YO, you can drop it off the needle, and pull out the slack later on if needs be.
To make the "head count" easier, I place stitch markers between repeats. Lace can be so much fun...but I have to prepare for it!
And, I don't try for speed with lace knitting. If I speed, then I make mistakes, and lose all the time on corrections...it never fails. I reduce distractions also.
I knit a beautiful icy pink angora lace scarf from my Stash in early January. (had the yarn for 5 years!) It is perfect! I might post a photo of it on our STASHIES thread. I started Stash Busting about a month before creating the Year of The Stash 2007 thread! So far, all I have posted is the Stash Projects completed after we started the thread.
Stash On, Sister!
