Hello!
How about ch 8, sl st in second ch from hook, sc in next ch, hdc in next ch, dc in next ch, tr in next ch, dtr in next ch, ttr in next chain. This makes a kind of funky, laddery triangle, worked from the tip down. I suppose you could work it from the bottom up as well. I haven't used too many triangles yet...as fillers when I have used them.
