Crochet in Rounds Tote Project

As I'm thinking about how I will teach this project, I am second guessing some of the choices I made regarding "1 hdc in same sp as last sl st" when I worked up my sample. I'd like to know what other people have done.

1. Since the sl st is worked into the first hdc of the round, I remember thinking it odd that the instruction was hdc in same space rather than same stitch. I didn't see where there would be a space so after ch2, I worked my first hdc into the same previous-row-hdc that was joined by the sl st. Is this what others have done or have I missed something?

2. This instruction is only included in rounds 2 and 3. Subsequent rounds say "Ch2, 1 hdc in each hdc around." Again I'm wondering what the difference is vs. this is just an inconsistency in how the pattern was written.

I liked the fact that using a small hook created a really sturdy fabric that will hold its shape. The tote is really cute except for the "seam" created where the rounds join. I see it on all three totes in the pattern photo as well as my own crocheted sample. Does anyone have suggestions for how to make the "seam" less obtrusive?

Thanks in advance,
Marian
