Help Please With a Pattern.. All Purpose Knitted Afghan

]I got this pattern free on the net (just Google the name and there it is!) very pretty…and looks simple
Only after I cast on the 210 required stitches and successfully worked (I thought) the first three rows… I realized… YIKES! something is not right!
So I tried to do a practice small version (Yes… it ought to have come first!) only I do not understand the 11+1 pattern …How many stitches do I cast on … to make a small three or four repeat of the pattern to practice?
also… I think I am doing the YO’s correctly… but on the next row… do I knit them or ignore them or…???
Any help is greatly appreciated…

To do a smaller size sample, say youwant 3 pattern repeats, cast on 3 x 11 and then add 1 more so 34 stitches. that will give you a size just like shown at the top of the pattern. If you want it 4 repeats wide, cast on 4 x 11 +1 = 45.

row 2 is the row after the yo row and it says to purl so you’ll purl the whole row. Don’t ignor the YOs, you need to purl them.
