Cardigan in progress photos

Having scuttled all previous planning and beginnings, i'm making progress on the design i finally settled upon. and it feels
liberating to be done with all the dithering i was doing. rather than follow a pattern, i've struck out on my own and will check
measurements of a favorite cardigan as i go along. i decided to make a bottom panel with random width stripes going vertically... and knit til it's big enough around. the next step is still a bit hazy in my mind, but i think i will pick up stitches
along the top of the panel, and knit up to the shoulders, doing decreases for a square neckline at the proper place. then
will cut down far enough for armholes, pick up stitches there and knit sleeves (maybe 3/4 length and straight??) note to self:
remember to do those extra stitches for the steek. the wonderful yarns i bought in the beginning are still in the plan, plus
a few handspun. here's some photos:
the (very) rough sketch

the bottom panel in progress

the knitted fabric and yarn

some of the not yet spun fiber and yarn from it. this
is merino, silk, mohair locks, tencel, sari waste thread and cashmere which i carded on my Duncan carder.

any words of wisdom on the design description? have i missed something?
