Well, I decided to just skip the slipping the first stitch on that one row, and it seems like it'll be fine. I dug around and searched on another board where others have knit this same pattern, and it sounds like it's not terribly crucial for the finished edge to skip the slip stitch. Someone else had accidentally forgotten to slip the first stitch a few times throughout the pattern, and the designer of the pattern told her it wasn't a big deal but just to make sure to only pick up one stitch when it comes to the crocheting. I'm not familiar with crocheting, so I don't totally understand that part yet but I assumed it'd be okay to not slip the first stitch for that one row if the designer of the pattern said it wasn't that big of a deal for someone who forgot to slip a few rows here and there. Anyway, I'm several rows down on the pattern now, and it seems to be going good.
Thanks for all the help. I'm sure I'll be back with more questions as I move through this pattern, but so far it's going good and seems to be a good stepping stone into a slightly more difficult pattern than what I've done so far..... which isn't saying much!
