First time hemming

Hi all! I've just recently finished my first counted cross stitch (the floret border bitkit) which I'm thrilled with. It's not perfect because I miscounted a few stitches but fortunately there are no glaringly obvious mistakes that throw off the whole design. I will still enjoy it as a decorative piece in my home, and I have to start somewhere, right?

I've watched Krista's video of how to do a drawn thread hem which was helpful but I'd like to keep things simple for this piece - is there a video I could be directed to on how to hand sew the hem without doing the drawn thread technique? That is, once I fold over and press the raw edges and do the mitrered corners what do I do next? What type of stitch should I be searching for and looking up? In the instructions that came with the kit it says you can do either a drawn thread technqiue or hem by hand using sewing thread and that videos are available on the Avlea website, but I can only see a video for drawn thread, nothing for just hemming by hand...does that make sense?

I am an absolute beginner in this area having never done it before, so please keep your explanations as simple as possible, many thanks everyone!
