This cardigan by Tålamodspåsen inspired me - thank you!
It wasn't difficult, but the wrong-side rows were rather slow to knit as I had to make sure the floats stayed on the wrong side facing me). I think it makes a nice frame.
Next step is picking up stitches to knit the sleeves. I may knit a simpler but similar flower pattern, perhaps just white flowers on blue background. The body pattern repeat is 40 stitches wide, possibly too wide for a sleeve. We'll see.
