Very nice!
Very nice! I like the yarn you chose.
It looks very pretty with that vibrant blue.
Looks great! If there is a way to avoid the curling edge hopefully we’ll learn about it because back when I was doing this technique regularly (over 30 years ago!) I never figured that out! I would do an edging or trim to make it lie flat. I also frequently lined it with fabric. Lol I never knew anything other than this stitch though. I’m excited to learn beyond the Simple Stitch!
I like your color choice.
So I don’t know what pulling your stitches to the top and not stopping at the front means. And how do you know how many sizes to go up? I know the rule of thumb is 2 but what do you look at to tell if that’s enough?
Well I’m going to have some curling until I learn the purl stitch on week 3. But I also seem to remember going up an additional hook size helped give that first pass some extra room. Is that not the case?
Thanks everyone for your kind words. I started another square using a 5.5mm and I think with the larger hook I am pulling the hook to the top of my work. Time will tell as I get a few more rows done. @TexasPurl thank you so for helping me along this process. It is awesome that you can look at a picture and help me.
My latest square attempt. 
Wow, that Brava Sport is so pretty with your stitching! Do you like the feel of that fabric better?
Yes!! If I had a thin cotton and wanted a dense dishcloth I would probably use the smaller hook. You are a wonderful inspiration and teacher. Thanks for all your help!!
PS. I forget to say how much fun I’m having.
Looks really good! Pretty color.
Finished my TSS. I used Knit Picks Stroll fingering weight yarn “Spectacular Speckles” and a size H/8-5.0mm hook from my Knitter’s Pride Dreamz Interchangeable crochet hook set. 30 stitches. The square has been blocked and the finished size is 5-1/2". I may (or not) put a crochet border on my squares. Looking forward to next week’s stitch!
I love the speckles!! Well done. I hope mine comes out as nice.
It is nearly time for me to go stash diving - I’m hoping to bring whatever masks I have done tomorrow or Wednesday for the start of school, and my needles are on the way - I suspect they’ll be here just in time for me to start. 
Your square is beautiful!
My TSS square is finished. The yarn is Bernat Baby Sport, the color doesn’t show up well, it is a pastel peach. I used an H hook, and chained 30 to begin. Squares are about 7-1/4”.
@TexasPurl, I do have a question - do your sample squares have a border, or is that what yours look like with just the TSS? My edges don’t look the same as yours. Also, I did use one size larger hook for the initial chains, but it ended up wider than the rest of the square. So I think I will just use the same size needle. Please let me know if you think my stitches are too tight or loose.
Looks very nice. I’m working on getting my edges neater but yours look great!
Pretty! I love those colors!
Yes ma’am, you have those edges down! Great work. It’s pretty.
Nice! I do like that yarn and your stitching is so neat. I’m going to have to practice!
