I am finishing a blanket that consists of 24 squares. Each square has "yarn over" stitches on each edge. The crochet border instructions say,
"Join yarn in any yo-loop. Work 2 sc in each yo-loop and 2 ch in each corner st. Join with sl st and fasten off."
I have two (maybe three) major questions.
1) I have very long tails from the individual squares all along the outside edges of the blanket. Rather than joining new yarn, can I use these tails to make the crocheted border?
2) I learned to crochet when I was a child and haven't done it since. I know that "sc" means single crochet and "ch" means chain. Beyond that little bit of knowledge, I can't really picture how to do this border
3) Can anyone help me with this or give me any idea of where I could look online to get some help?
Thanks! I've been working on this blanket for over a year and a half, and would like to be able to finish it.
If it helps, here is a picture of one 4-square segment of the blanket. The blanket is 6 of these 4-square segments (2x3), but each square was knitted exactly the same. So this 4-square segment is just a mini-version of the whole blanket. It's kind of hard to see the loops (on the bottom edge of the segment they're the most visible), but they're on all sides.
