Rather than doing rows, try Catherine Hirst's tutorial for doing a granny square see here I heart her, she taught me, and I found going round MUCH easier, it made sense, still can't manage a square of rows of crochet that doesn't have a frilly edge.
If you did squares in different colours in that zingy wool of yours it would be really effective when all attached.
Try looking on YouTube for crochet tutorials - that's how I learned to crochet a basic granny square - and from there, I went back to the written granny square pattern! and knowing how to do it meant I could work back from that to understand following the pattern.
Once I did that, I found it was much easier to follow other patterns.
My lovely wool arrived today & I was all excited but I'm now feeling overwhelmed! I've spent ages on Ravelry & Pinterest but could do with a simple pattern to follow to get me started - using a 4mm hook. Unless someone can tell me roughly how many to chain to get me started. I've tried several times but my brain is addled & I'm disappointed that I've not yet got a pile of beautiful squares that I've made.
