With an end to end shawl, you want one edge straight and one edge increasing. Or do you want it bottom up?
These 2 rows - Row: yo, K1, yo and Row: K1, *yo, k2tog*, yo - won't work, you need an edge st with the YOs inside them. Maybe you meant - k yo k yo k on that first one which gives you 5 sts, then next would be: K1, P2, K1 and on the follow row - k, yo k2tog, yo, k2 tog.
What's a fat 'cursivated' YO? A yo is a YO, and its size depends on the needle size and how loose or tight you make it.
