HELP! Sewing Notched Collar and Lapels?

[OkamiKodomo]

I'm almost done with a jacket I've been working on for Rune (RS Jun) ... All I need is the collar. I want it to look something like this: link in shape and size... But I'm at a loss x.x I'm working with a fairly sturdy cotton, so I'd rather not use interfacing if I can avoid it, but will if I must.

I would sew it wrong-side, cut off the seam allowance at the tips so they don't distort your tips, flip it right side, and once you have them the way you want then sew the secondary row on the right side and attach it to the coat. Does that make sense? Sorry, I'm bad at explaining things. ^^;

If the fabric is stiff then it shouldn't need interfacing to keep the shape being that small, but if it's too floppy I'd just do a little bit on one side near the weak point so it doesn't get too stiff.

Thanks so much for the tips... I did end managing to figure it out, though they came out a bit uneven ^_^; I'm happy with the result anyway.
