ribbed tuck lace or tuck lace rib...

I knocked off that skirt, no problem and I'm on a roll - looked around for something else to do...I have a ribber class to do in Minneapolis as well as the seaming techniques for the manfriend hoodie which was all single bed, so I think I should do a project on the double bed just for a bit of practise. Oh, I know, I mentioned after San Diego that I would like to use that tuck lace rib stitch that was in the old cover garment tunic from 1994 (blogpost, cover story, May 20, 2015).
You may have noticed that I have an affinity for cardigans - rarely do I make a pullover, so it's kind of a given here. I like cardigans because they give me more wardrobe options and to be honest, I always feel fat in a pullover. The illusion of a small waist is easier to maintain with the vertical lines down the centre of the button front, open or closed. You'd think I'd get over it one day but it doesn't look like to  be happening soon, so, cardigan it is!
I want this to be really lightweight,  MSP can be very hot and humid in late July, so I've chosen Wool Crepe Deluxe - I have 2 family weddings in September and this could be a good option for at least one of the associated events. I made the first swatch and as I was knitting it, I remembered one of the problems with this tuck lace is that it tends to lengthen and narrow and, as it is WCD that I'm using, which is usually at 34 to 38 stitches/10 cm that could make more trouble than it's worth.
I also want the lacy holes to stay open and not get dragged down as the fabric narrows. I throw on the 'tuck-every-other-row' option on the ribber and wow, what a difference! not only takes the stitch gauge from 49 sts/10 cm (top swatch) to 35 sts/10 cm, but adds a flatness and width stability to the fabric. A few tweaks to my cast-on edge so it's easier to rehang and add one of my favourite trims (a variation of #33 XOXO trim from Band Practise) and I have a plan!
