Playing with lace

I became intrigued by a Japanese book I bought recently, of patterned lace, and wondered if I could use a pattern in the book to make an interesting summer tank top/vest thingie. So, I swatched ( in leftover blue Cotton Classic, no.6 US needles, which I had on hand) , calculated and cast on provisionally, for a bottom-up circular tank, figuring I'd knit till long enough, divide for armholes, plug in a V-neck and bind off sloping shoulders, and decide on the edge treatments later..
Of course, after about 4 inches, the pattern seemed way too busy, so I simplified it and decided the bottom was a border, and continued in pattern up the trunk. I'm liking the effect, and having fun seeing what comes next. I'm also going down some needle sizes( 5 then 4, then 5 and 6 again) to create waist shaping. I hope it comes out as I envision, but the journey is sometimes more interesting than the destination...
