For a hat you should do ribbing on the bottom mostly - so there will be knit and purl.
And you either need to increase or decrease...
So you will need a BIT more than just knits. But it is all doable and a good next step.
The Felicity-Link did not work on my PC here, so I googled it and found it here.
maybe this will work.
Or maybe this one?
Signing up to ravelry if for free, so you might want to do that for patterns and info. Give it a try.
Also this one here (just knit all the stitches instead of the mesh-pattern)Garnstudio - Drops design
round 1 would be then: knit all stitches. Round 2 would be the same.
or you learn the mesh pattern - not hard, really.
maybe that is something for your idea?
